Exhibit 99.1

          VISHAY AND INTERNATIONAL RECTIFIER ANNOUNCE AGREEMENT FOR THE
                   SALE OF IR'S POWER CONTROL SYSTEMS BUSINESS

    MALVERN, Pa. and EL SEGUNDO, Calif., Nov. 1 /PRNewswire-FirstCall/ -- Vishay
Intertechnology, Inc. (NYSE: VSH) and International Rectifier Corporation (IR)
(NYSE: IRF) today announced they have reached an agreement for the sale of IR's
Power Control Systems (PCS) business to Vishay. The PCS business includes IR's
Non-Focus Products business and certain product revenue from its Focus Products
business, including certain discrete planar MOSFETs, discrete diodes and
rectifiers, discrete thyristors, and automotive modules and assemblies. The PCS
business accounted for revenue of approximately $300 million, or 26% of revenues
in IR's June-ending fiscal year 2006. The PCS business is expected to be sold
for approximately $290 million in cash. The agreement is subject to customary
closing conditions, including obtaining all necessary governmental approvals and
clearances, and finalization of certain documentation. Signing of definitive
agreements is expected to take place by Friday, November 10, 2006, and the
transaction is expected to close in February 2007.

    For Vishay, the acquisition extends its product offering in discrete
semiconductors and modules, while enhancing its strong position as one of the
industry's largest manufacturers of discrete semiconductors and passive
components. Furthermore, this acquisition will provide Vishay with synergies in
the area of modules by combining Vishay components with the product lines to be
acquired from International Rectifier. This divestiture enables International
Rectifier to concentrate more fully its resources and assets on its Focus
Products business, which includes high-performance analog, digital, and
mixed-signal ICs, and other advanced power management products.
