Item 1.01 Entry into a Material Definitive Agreement

International Rectifier Corporation (the “Registrant”) previously reported entering into a Credit Agreement (the “Revolver Agreement”), dated as of November 6, 2006, among the Registrant, certain lenders and JPMorgan Chase Bank, National Association (“JPMorgan”), as Administrative Agent (such lenders and JPMorgan, together, the “Revolver Banks”), providing for, among other things, a revolving credit facility with total commitments in the principal amount of $150,000,000, and an Amendment No. 1 to the Revolver Agreement dated May 4, 2007.

On June 27, 2007, the Registrant and the Revolver Banks entered into Amendment No. 2 to the Revolver Agreement (the “Revolver Amendment”), providing for the Revolver Banks’ agreement that, in light of the ongoing previously disclosed investigation, conducted at the request of the Audit Committee of its Board of Directors by independent investigators hired by outside legal counsel, the Company will not be deemed in default in respect of certain representations, warranties, covenants and reporting requirements during a period ending not later than September 15, 2007 (the “Amendment Period’’). During this period, the Revolver Banks will be entitled to assert that lending conditions under the Revolver Agreement have not been satisfied in respect of credit extensions. A copy of such Revolver Amendment is attached as Exhibit 99.1 hereto.

At June 27, 2007, the Registrant had no borrowings and approximately $4.3 million in letters of credit outstanding under the Revolver Agreement. As set forth in the Revolver Amendment, the Registrant has agreed to cash collateralize any outstanding letters of credit and the Registrant paid an amendment fee to the Revolver Banks. The Registrant believes it appropriate to have credit facilities available to meet working capital and other needs that may arise although it currently does not anticipate accessing those facilities over the near term other than the existing outstanding letters of credit.

The foregoing descriptions are not complete and are qualified in their entirety by reference to the Revolver Amendment which is filed as Exhibit 99.1 hereto and incorporated herein by this reference.

Cautionary Information Regarding Forward-looking Statements

This Form 8-K includes some “forward-looking statements” as that term is defined in the Private Securities Litigation Reform Act of 1995. The forward-looking statements can be identified by the use of forward-looking terminology such as “anticipate” and “believe.” Such forward-looking statements include, among other things, our statement that the Registrant does not anticipate accessing its credit facilities under its revolving credit line over the near term other than the existing outstanding letters of credit. Forward-looking statements are subject to a number of uncertainties and risks, and actual results may differ materially from those projected. Factors that could affect the Registrant’s actual results include unanticipated needs for working capital or credit facilities beyond the Registrant’s current financial resources and the effects of other various risk factors and uncertainties disclosed in the Registrant’s reports filed with the

Securities and Exchange Commission, including its most recent reports (not including financial information) on Forms 10-K and 10-Q. Such forward-looking statements speak only as of the date on which they are made, and the Registrant does not undertake any obligation to update any forward-looking statement to reflect events or circumstances after the date hereof.

(b) On July 1, 2007, the employment of Michael P. McGee, Executive Vice President and Chief Financial Officer of the Registrant was terminated by the Registrant’s Board of Directors. As described in Item 5.02(c) below, the Registrant’s Board of Directors appointed Linda J. Pahl, previously Vice President, Corporate Finance of the Registrant, as acting Chief Financial Officer, effective upon the departure of Mr. McGee.

On July 1, 2007, Robert Grant, Executive Vice President, Global Sales and Marketing, of the Registrant resigned. Alexander Lidow, the Registrant’s Chief Executive Officer, shall assume the duties of Executive Vice President, Global Sales and Marketing until a successor to Mr. Grant is appointed.

(c) The Registrant’s Board of Directors appointed Linda J. Pahl, as acting Chief Financial Officer, effective upon the departure of Mr. McGee as described in Item 5.02(b) above.

Ms. Pahl is 46 years old and joined the Registrant in January 1999 as Director of Global Finance. Since joining the Registrant, Ms. Pahl served the Registrant in various financial roles, most recently as Vice President, Corporate Finance since April 2006. Prior to joining the Registrant, Ms. Pahl was Vice President and Chief Financial Officer of Blue Cross of California at Wellpoint Health Networks, Inc.

The Registrant has advised Ms. Pahl that her salary, bonus opportunity and equity incentives during the period that she will serve as acting Chief Financial Officer will be negotiated as appropriate to align them with the duties and responsibility of the Chief Financial Officer position. The Registrant intends to file a copy or summary of the material terms of such arrangements promptly following their formalization.

Except as disclosed herein, Ms. Pahl was not selected pursuant to any arrangement or understanding between Ms. Pahl and any other person. There are no family relationships between Ms. Pahl and the directors or executive officers of the Registrant.

On April 9, 2007, the Registrant announced that it was conducting an internal investigation of accounting irregularities, being carried out by independent investigators hired by outside legal counsel at the request of the Audit Committee of the Board of Directors of the Registrant. That investigation continues as of the date of this report.
