PROXY STATEMENT

SOLICITATION OF PROXY, REVOCABILITY AND VOTING

General

The enclosed Proxy is solicited on behalf of the Board of Directors (the “Board” or “Board of Directors”) of Supertex, Inc., a California corporation (the "Company"), for use at the 2005 Annual Meeting of Shareholders to be held on August 19, 2005 at 10:00 a.m., local time (the “Annual Meeting”), or at any adjournment thereof, for the purposes set forth herein and in the accompanying Notice of Annual Meeting of Shareholders.

The Annual Meeting will be held at the principal offices of the Company located at 1235 Bordeaux Drive, Sunnyvale, California 94089. The Company's telephone number at that address is (408) 222-8888.

The Company is mailing this proxy statement and an accompanying proxy card on or about July 19, 2005 to all shareholders entitled to vote at the Annual Meeting.

Revocability of Proxies

Any proxy given pursuant to this solicitation may be revoked by the person giving it at any time before its use (i) by delivering to the Secretary of the Company at the Company’s principal executive offices, 1235 Bordeaux Drive, Sunnyvale, California 94089 a written notice of revocation or a duly executed proxy bearing a later date or (ii) by attending the meeting and voting in person. Attendance at the meeting will not, by itself, revoke a proxy.

Solicitation

The Company will bear the entire cost of preparing, assembling, printing and mailing this Proxy Statement, the accompanying proxy and any additional material that may be furnished to shareholders. Copies of solicitation material will be furnished to brokerage houses, fiduciaries and custodians to forward to beneficial owners of stock held in the names of such nominees. The Company may retain the services of an outside proxy solicitation firm at an estimated cost of approximately $10,000 to $15,000. The solicitation of proxies may also be made by the use of the mails and through direct communication with certain shareholders or their representatives by officers, directors and employees of the Company, who will receive no additional compensation for such solicitation. This proxy and the accompanying form of proxy are being mailed to shareholders on or about July 19, 2005.

Voting

Only shareholders of record at the close of business on June 24, 2005 (the "Record Date") are entitled to notice of and to vote at the meeting. On the Record Date, 13,061,768 shares of the Company's Common Stock, no par value, were issued and outstanding. Therefore, the presence at the Annual Meeting, either in person or by proxy, of a majority or 6,530,884 shares of Common Stock will constitute a quorum for the transaction of business at the Annual Meeting. Every shareholder voting at the election of directors may cumulate such shareholder's votes and give one candidate a number of votes equal to the number of directors to be elected multiplied by the number of votes to which the shareholder's shares are entitled, or distribute the shareholder's votes on the same principle among as many candidates as the shareholder thinks fit, provided that votes cannot be cast for a greater number of candidates than the number of directors to be elected. However, no shareholder shall be entitled to cumulate votes unless the candidate's name has been placed in nomination prior to the voting and the shareholder, or any other shareholder, has given notice at the meeting prior to the voting of the intention to cumulate the shareholder's votes. On all other matters, each share has one vote. The director candidates who receive the most votes will be elected to fill the seats on the Board. Approval of all of the proposals requires the favorable vote of a majority of the votes “represented and voting” at the Annual Meeting (the “Votes Cast”). An automated system administered by the Company's transfer agent, Registrar and Transfer Company, tabulates the votes.

Quorum; Abstentions; Broker Non-Votes

The required quorum for the transaction of business at the Annual Meeting is a majority of the shares of Common Stock issued and outstanding on the Record Date. Shares that are voted "FOR", "AGAINST" or "WITHHELD FROM" a matter are treated as being present at the meeting for purposes of establishing a quorum and are also treated as shares "represented and voting" at the Annual Meeting (the "Votes Cast") with respect to such matter.

While there is no definitive statutory or case law authority in California as to the proper treatment of abstentions, the Company believes that, in the absence of contrary controlling authority, abstentions should be counted for purposes of determining the presence or absence of a quorum for the transaction of business, but should not be counted as Votes Cast with respect to a proposal, since the shareholder has expressly declined to vote on such proposal. Similarly, broker non-votes will be counted for purposes of determining the presence or absence of a quorum for the transaction of business, but will not be counted for purposes of determining the number of Votes Cast with respect to the proposal on which the broker has expressly not voted. A broker “Non-Vote” occurs when a nominee holding shares for a beneficial owner does not vote on a particular proposal because the nominee does not have discretionary power with respect to that item and has received no instruction from the beneficial owner.

Accordingly, in general abstentions and broker “non-votes” will not affect the outcome of the voting on a proposal that requires a majority of the Votes Cast. However, the number of shares voting in favor of any matter must constitute at least a majority of the required quorum for the Annual Meeting.

Deadline for Receipt of Shareholder Proposals

Proposals of security holders of the Company which are intended to be presented by such shareholders at the Company's 2006 Annual Meeting must be received by the Company no later than March 20, 2006 in order to be considered by the Company’s management to be included in the proxy statement and form of proxy relating to that meeting. The proposal must be mailed to the Corporate Secretary of the Company at our principal offices, 1235 Bordeaux Drive, Sunnyvale, California 94089. Such proposals may be in next year’s proxy statement if they comply with the certain rules and regulations promulgated by the Securities and Exchange Commission.

A shareholder proposal not included in the Company’s proxy statement for the 2006 Annual Meeting will be ineligible for presentation at the meeting unless the shareholder gives timely notice of the proposal in writing to the Secretary of the Company at our principal offices. To be timely, the Company must have received the shareholder’s notice no later than June 5, 2006.

PROPOSAL 1: ELECTION OF DIRECTORS

Nominees

The nominees for the upcoming election of directors include three independent directors, as defined in the listing standards of the Nasdaq Stock Market, Inc.

BOARD OF DIRECTORS AND COMMITTEES

Corporate Governance

We are committed to the principles of sound corporate governance. Our Board of Directors has adopted corporate governance guidelines to assist it in fulfilling its responsibilities to shareholders and to our employees, customers, suppliers, and local communities in which we operate. Our corporate governance guidelines together with our current committee charters are available free of charge, in the “Corporate Governance” section of our website at www.supertex.com. Written requests should be directed in writing to Supertex, Inc., 1235 Bordeaux Drive, Sunnyvale, CA 94089, Attention: Investors Relations.

Our policies and procedures reflect corporate governance initiatives that are in compliance with the corporate governance requirements of the Sarbanes-Oxley Act of 2002 and the listing requirements of the Nasdaq, including:

·	The board of directors has adopted clear corporate governance policies;

·	Three of our five board members are independent of us and our management;

·	The independent directors meet regularly without the presence of management;

·	All members of the audit and corporate governance committee and the executive compensation committee are independent directors;

·	The board of directors has elected W. Mark Loveless as lead director to preside over the executive sessions of the independent directors.

·	The charters of the board committees clearly establish their respective roles and responsibilities;

·	We have a hotline available to all employees, and our audit and corporate governance committee has procedures in place for the anonymous submission of any employee complaint, including those relating to accounting, internal controls, or auditing matters; and

We have a Code of Business Conduct and Ethics that applies to the Board of Directors and all of our employees, agents and contractors, including the Chief Executive Officer and Chief Financial Officer and Controller.

Board Responsibilities and Structure

The primary responsibility of the Board is to provide effective governance over the Company’s affairs for the benefit of the Company’s shareholders, employees, customers and suppliers, and local communities. The Board’s responsibilities include but are not limited to (a) evaluating the overall performance of Supertex and its business; (b) reviewing strategic plans, approving capital spending, and budgets; (c) monitoring risks such as litigation and competitive threats, and evaluating management’s plans for dealing with such risks; (d) evaluating the performance of the Chief Executive Officer; (e) establishing compensation policies for the Chief Executive Officer and other executive officers; (f) reviewing succession plans and development programs for members of management; (g) reviewing corporate policies regarding legal and ethical conduct; and (h) evaluating itself in terms of size, independence, and overall effectiveness.

It is the policy of the board of directors that a majority of the directors be independent. Currently, three of our five directors meet the standards of independence as defined by current Nasdaq listing standards and SEC rules. The Board has determined that Directors W. Mark Loveless, Elliott Schlam and Milton Feng are independent. Directors Henry C. Pao and Richard E. Siegel are employed by the Company and thus do not meet the independence standards.

The Board has an Audit and Corporate Governance Committee, an Executive Compensation Committee, and a Compensation Committee, and the Board has adopted a written charter for each of these committees. The Board has no nominating committee, however the Board has delegated to the Audit and Corporate Governance Committee the functions of a nominating committee.

The Board of Directors of the Company held a total of two formal Board meetings during the fiscal year ended April 2, 2005. All directors attended all the meetings of the Board and of the committees on which such directors serve.

In addition, the board of directors has determined that W. Mark Loveless meets the criteria of an “audit committee financial expert” within the meaning of the SEC’s regulations. In fiscal year 2005, the Audit and Corporate Governance Committee held five meetings. All members of the Audit and Corporate Governance Committee attended all five meetings.

On behalf of the Board of Directors, the Audit and Corporate Governance Committee (1) retains the Company’s independent accountants, (2) reviews the arrangements for and scope of the audit by the Company’s independent accountants and reviews their independence, and (3) generally oversees the integrity and quality of the Company’s financial accounting and reporting practices and its system of internal accounting controls. It is not the duty of the Audit and Corporate Governance Committee to plan or conduct audits or to determine that the Company’s financial statements are complete and accurate and are in accordance with generally accepted accounting principles. Management is responsible for the Company’s financial statements and the reporting process, including the system of internal controls. The independent auditors are responsible in their report for expressing an opinion on the conformity of those financial statements with generally accepted accounting principles.

The Audit and Corporate Governance Committee is also chartered to oversee the corporate governance compliance and director nominations. Specifically, they are (1) to identify individuals qualified to become Board members and to nominate directors for election; (2) to lead the Board in its annual review of the Board's performance; (3) to recommend to the Board director nominees for each committee; and (4) to review and make recommendations to the Board concerning corporate governance matters.

The current members of the Executive Compensation Committee are W. Mark Loveless, Elliott Schlam, and Milton Feng, each of whom are “independent” as defined by current Nasdaq listing standards and SEC rules. No meetings of the Executive Compensation Committee were held during fiscal year 2005, however the committee acted on two resolutions by unanimous written consent.

The purpose of the Executive Compensation Committee shall be to evaluate and approve the compensation of the CEO and other executive officers and to provide oversight of the Company’s compensation policies, plans and benefits programs, including the granting of stock options to all employee directors and executive officers. The Executive Compensation Committee also acts as the Administrator of the Company’s Supplemental Executive Retirement Plan and the Employee Stock Purchase Plan.

The Compensation Committee also serves as the Stock Option Committee under the Company’s Stock Option Plan for granting of options to all employee and consultants, other than employee directors and executive officers.

Compensation Committee Interlocks and Insider Participation

Messrs. Loveless, Schlam and Feng serve as members the Executive Compensation Committee. No interlocking relationship exists between the Board of Directors or Executive Compensation Committee and the board of directors or compensation committee of any other entity, nor has any interlocking relationship existed in the past.

Director Compensation

The Company currently pays cash compensation to its outside Directors for serving on the Board in an amount of $1,000 for each Board meeting attended. The Chairman of the Audit and Corporate Governance Committee receives an additional $1,000 for each Audit and Corporate Governance Committee meeting, while the Audit and Corporate Governance Committee members receive $500 for each meeting. The Company also reimburses all outside Directors for travel and other necessary out-of-pocket expenses incurred in the performance of their services as directors. In addition, the Company pays its outside directors an annual retainer of $10,000 for the “Audit Committee Financial Expert” and $5,000 for the other outside directors.

Nomination of Directors

The Audit and Corporate Governance Committee nominates candidates for election to the Board based on an evaluation of the candidate’s decision-making ability, business experience and expertise, technological background, personal integrity, reputation, ability and willingness of the candidate to devote the necessary time to board service on an ongoing basis, and independence as defined by Nasdaq listing standards. The Audit and Corporate Governance Committee also reviews the activities and associations of potential candidates to ensure that there is no legal impediment, conflict of interest, or other consideration that might hinder or prevent the potential candidate from fulfilling the duties of a director. When the Audit and Corporate Governance Committee considers whether to nominate current members of the Board of Directors for reelection by the shareholders, it also considers each member’s contributions to the Board of Directors and the Company, the member’s knowledge of the Company and issues presented to the Board of Directors, and the member’s preparation for meetings and meeting attendance records.

The Audit and Corporate Governance Committee does not currently use the services of a third party consultant to assist in the identification or evaluation of potential director candidates. However, it may engage a third party to provide for such services in the future.

The Audit and Corporate Governance Committee will consider prospective nominees for election to the Board of Directors that are proposed by shareholders based on the same criteria it uses for all director candidates. Any shareholder who wants to recommend a prospective nominee for the Audit and Corporate Governance Committee’s consideration should submit the candidate’s name and qualifications to the Audit and Corporate Governance Committee Chairman via e-mail at audit@supertex.com, or by fax to (408) 222-4805. The deadline for shareholders to submit their recommendation for a prospective nominee should be received by the Audit and Corporate Governance Committee no later than March 20, 2006, the same deadline for the submission of proposals for the 2006 Annual Meeting.

Certain Relationship and Related Transactions

The Company leased a portion of a building, consisting of approximately 5,600 sq. ft at 1225 Bordeaux Drive, Sunnyvale, California under an operating lease from Fortuna Realty Co, a corporation owned by a former Supertex Director, Yunni Pao, who also owns Push Inc., a company who beneficially owns more than 10% of the Company’s Common Stock, as more fully set forth in the following page under “Securities Ownership of Certain Beneficial Owners and Management.” The lease will expire on April 1, 2007, which coincides with our Sublease Agreement with Reaction Technology, our epitaxial deposition service provider at essentially the same cost. Previously we leased the entire building, consisting of approximately 20,000 sq.ft. The total rental expenses paid to Fortuna Realty Co. were $125,000, $125,000, and $130,000 in fiscal years 2005, 2004 and 2003, respectively. We believe that the lease with Fortuna Realty Co. was and is at prevailing market rates.

Mr. Richard Siegel, the Executive Vice President of the Company, is a member of the Board of Directors for All American Semiconductor. All American Semiconductor is a national distributor of electronic components manufactured by others and is a major distributor for Supertex.

Report of the Executive Compensation Committee

of the Board of Directors

Notwithstanding anything to the contrary set forth in any of the Company’s previous filings under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended, that might incorporate future filings, including this Proxy Statement, in whole of report, the following report shall not be deemed to be incorporated by reference into any such filings.

The Executive Compensation Committee of the Board of Directors is generally responsible for reviewing compensation and benefits, including stock options, of executive officers of the Company. All the members of the Board of Directors review the stock compensation of outside directors.

The Company applies a consistent philosophy of compensation for all employees, including its executive officers. This philosophy is based on the premise that the achievements of the Company result from the coordinated efforts of all individuals working toward common objectives. The Company strives to achieve those objectives through teamwork that is focused on meeting the defined expectations of customers and shareholders.

Compensation Philosophy. The goals of the committee are to align executive compensation with business objectives and performance, and to enable the Company to attract, retain and reward executive officers who contribute to the long-term success of the Company. The Company's compensation program for the chief executive officer and other executive officers is based on the same four principles applicable to compensation decisions for all employees of the Company:

The Company pays competitively. The Company is committed to providing a compensation program that helps attract and retain the best people in the industry. To ensure that pay is competitive, the Company reviews the compensation practices of other companies of similar size and sales volume within the semiconductor industry, most of which are included in the Nasdaq Electronic Component Index.

The Company pays for relative sustained performance. Executives are rewarded based upon corporate performance, product line performance, and individual performance. Corporate performance and product line performance are evaluated by reviewing the extent to which strategic and business plan goals are met, including such factors as operating profit, performance relative to competitors and timely new product introductions. Individual performance is evaluated by measuring organization progress against set objectives.

The Company strives for fairness in the administration of compensation. The Company strives to achieve a balance with respect to compensation paid to the executives within the Company and in comparable companies. The Company also believes that the contributions of each member of the executive staff are vital to the success of the Company. As such, the Executive Compensation Committee's current policy is that the CEO's base compensation does not have any bearing on the base compensation of the other officers. Similarly, any employee may receive a base compensation higher than his/her supervisor due to the particular higher technical skills required in the subordinate position.

The Company believes that employees should understand the performance evaluation and compensation administration process. At the beginning of each focal review period in December, annual objectives for the Company are set for each officer. The CEO gives ongoing feedback on performance to each executive officer. After the end of each fiscal year, the committees evaluate the accomplishments of the key objectives, which affects decisions on merit increases and stock option grants.

Compensation Components. The Company's compensation program, which consists of cash and equity based compensation, allows the Company to attract and retain highly skilled officers, provide useful products and services to customers, enhance shareholder value, motivate technological innovation and adequately reward its executive officers and other employees. These components are:

Cash-Based Compensation:

Salary. The Executive Compensation Committee sets base salary for the chief executive officer and executive officers by reviewing the compensation levels for competitive positions in the market. Based on comparative data, the chief executive and other executive officers were compensated within the low-to-middle salary range levels during fiscal 2005. The chief executive and executive officers of the Company largely met their individual goals and the Company's overall performance set for them in fiscal year 2005.

Profit-Sharing Bonus. The Company has a semiannual profit-sharing plan under which it distributes to all employees, including the chief executive officer and all other officers, ten percent of its operating profits before taxes and other adjustments. The Company believes that all employees share the responsibility of achieving profits. Accordingly, it awards a bonus to all employees based on a formula, which includes employment grade level, seniority with the Company, and employee performance including attendance. As of June 24, 2005, the Company has made twenty-seven semiannual profit-sharing distributions. There was one profit-sharing distribution in fiscal year 2005.

Equity-Based Compensation:

Stock Option Grants. Stock options provide additional incentives to the chief executive officer and all other officers, directors, and certain management and technical employees to work to maximize stockholder value. The options vest over a defined period to encourage such employees to continue in the employ of the Company. In line with its compensation philosophy, the Company grants stock options commensurate with the employee's potential contribution to the Company, measured by his qualifications and previous work performance. Stock options were granted to existing employees for performance and promotions, and as a part of the employment compensation package for new employees.

Chief Executive Officer Compensation

Mr. Henry C. Pao is the Company’s Chief Executive Officer. In accordance with the compensation philosophy stated above and the Company’s results, Mr. Henry C. Pao’s base salary during fiscal year 2005 was $290,098. His base salary is designed to be competitive with base salaries paid to other chief executive officers of corporations with similar size and sales volume within the semiconductor industry, most of which are included in the Nasdaq Electronic Component Index, although Mr. Henry C. Pao has the added responsibility of the Company’s Chief Financial Officer without extra compensation.

The Executive Compensation Committee establishes performance goals and objectives for the CEO each year and assesses his accomplishments of previously established objectives on a yearly basis. Company performance is a significant portion of each year’s objectives, with the remaining elements reflecting matters most important to the Company. This process is the basis for determining the amount of any bonus awarded to the CEO. Mr. Henry C. Pao received a bonus of $18,000 in fiscal year 2005.

As to the equity component of his compensation, the Executive Compensation Committee granted Mr. Henry C. Pao 10,000 options during fiscal 2005.

The Audit and Corporate Governance Committee is comprised entirely of outside, independent directors. On behalf of the Board of Directors, the Audit and Corporate Governance Committee retains the Company’s independentregistered public accounting firm (“External Auditors”), reviews the arrangements for and scope of the audit by the Company’s External Auditors and reviews their independence, and generally oversees the integrity and quality of the Company’s financial accounting and reporting practices and its system of internal accounting controls. It is not the duty of the Audit and Corporate Governance Committee to plan or conduct audits or to determine that the Company’s financial statements are complete and accurate and are in accordance with generally accepted accounting principles. Management is responsible for the Company’s financial statements and the reporting process, including the system of internal controls. The External Auditors are responsible in their report for expressing an opinion on the conformity of those financial statements with generally accepted accounting principles.

During the fiscal year ended April 2, 2005, the Committee met five times, and discussed the interim financial information contained in each quarterly earnings announcement with the chief financial officer, controller and PricewaterhouseCoopers LLP, our External Auditors, prior to public release.

In discharging its oversight responsibility as to the audit process, the Committee obtained from PricewaterhouseCoopers LLP the written disclosures and the letter from the External Auditors required by the Independence Standards Board Standard No. 1, "Independence Discussions with Audit and Corporate Governance Committees," has discussed with the PricewaterhouseCoopers LLP their independence and has satisfied itself as to the auditors' independence. The Committee also discussed with management, and PricewaterhouseCoopers LLP the quality and adequacy of the Company's internal controls. The Committee reviewed with PricewaterhouseCoopers LLP their audit plans, audit scope and identification of audit risks.

The Committee discussed with PricewaterhouseCoopers LLP all matters required to be discussed as described in Statement on Auditing Standards No. 61, as amended, "Communication with Audit Committees" and, with and without management present, discussed and reviewed the results of the External Auditors’ examination of the financial statements.

The Committee reviewed the audited financial statements of the Company as of and for the fiscal year ended April 2, 2005, with management and PricewaterhouseCoopers LLP. Based on this review and the above-mentioned discussions with management and PricewaterhouseCoopers LLP, the Committee recommended to the Board that the Company's audited financial statements be included in its Annual Report on Form 10-K for the fiscal year ended April 2, 2005, for filing with the Securities and Exchange Commission.

Each of the members of the Audit and Corporate Governance Committee is independent as defined in Rule 4200(a)(14) of the National Association of Securities Dealers' Marketplace Rules.
