Accounting Policies [Abstract]

Basis of Accounting, Policy [Policy Text Block]

The accompanying interim unaudited condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements. The unaudited condensed consolidated financial statements include the accounts of IXYS Corporation and its wholly-owned subsidiaries. The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and judgments that affect the amounts reported in the financial statements and accompanying notes. The accounting estimates that require management’s most difficult judgments include, but are not limited to, revenue reserves, inventory valuation, accounting for income taxes, and allocation of purchase price in business combinations. All significant intercompany transactions have been eliminated in consolidation. All adjustments of a normal recurring nature that, in the opinion of management, are necessary for a fair statement of the results for the interim periods have been made. The condensed balance sheet as of March 31, 2015 has been derived from our audited balance sheet as of that date. It is recommended that the interim financial statements be read in conjunction with our audited consolidated financial statements and notes thereto for the fiscal year ended March 31, 2015, or fiscal 2015, contained in our Annual Report on Form 10-K. Interim results are not necessarily indicative of the operating results expected for later quarters or the full fiscal year.

New Accounting Pronouncements, Policy [Policy Text Block]

In April 2014, the Financial Accounting Standards Board, or FASB, issued changes to the criteria for determining which disposals are required to be presented as discontinued operations. The changes require a disposal of a component of an entity or a group of components of an entity to be reported in discontinued operations if the disposal represents a strategic shift that has, or will have, a major effect on an entity’s operations and financial results. The amendments apply on a prospective basis to disposals of components of an entity that occur within annual periods beginning on or after December 15, 2014 and interim periods within those years, with early adoption permitted. We expect this guidance to have an impact on our financial statements only in the event of a future disposition which meets the criteria.

In May 2014, FASB issued a new standard on the recognition of revenue from contracts with customers, which includes a single set of rules and criteria for revenue recognition to be used across all industries. The revenue standard’s core principle is built on the contract between a vendor and a customer for the provision of goods and services. It attempts to depict the exchange of rights and obligations between the parties in the pattern of revenue recognition based on the consideration to which the vendor is entitled. To accomplish this objective, the standard requires five basic steps: identify the contract with the customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract, and recognize revenue when or as the entity satisfies a performance obligation. This standard is effective for annual reporting periods beginning after December 15, 2017, including interim periods during the annual period. Early adoption is prohibited for annual periods commencing before December 15, 2016. Different transition methods are available — full retrospective method, retrospective with certain practical expedients, and a modified retrospective (cumulative effect) approach. We are currently evaluating the impact of the adoption of the standard on our consolidated financial statements including selection of the transition method.

In August 2014, FASB issued a new standard on the disclosure of uncertainties about an entity’s ability to continue as a going concern. The guidance seeks to define management’s responsibility to decide whether there is substantial doubt about an organization’s ability to continue as a going concern and to provide related footnote disclosures. This standard is effective for annual reporting periods beginning after December 15, 2016, including interim periods during the annual period. Early application is permitted. We do not believe that the adoption of this guidance will have any material impact on our financial position or results of operations.

In April 2015, FASB issued the authoritative guidance that requires debt issuance costs related to a recognized debt liability to be presented in the balance sheet as a direct deduction from the debt liability rather than as an asset. The guidance will be effective for public companies for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods during the annual period, with early adoption permitted for financial statements that have not been previously issued. The new standard is required to be applied retrospectively to all prior periods presented in the financial statements. An entity is also required in the year of adoption (and in interim periods within that year) to provide certain disclosures about the change in accounting principle, including the nature of and reason for the change, the transition method, a description of the prior-period information that has been retrospectively adjusted and the effect of the change on the financial statement line items (that is, debt issuance cost asset and the debt liability). We do not expect this guidance to have a significant impact on our consolidated financial statements.
