    SILICONIX SPECIAL COMMITTEE APPOINTS INVESTMENT BANK AND LEGAL ADVISOR

         Santa Clara, CA--March 16, 2001--Siliconix incorporated (NASDAQ
NMS:SILI) announced today that the special committee of its Board of Directors,
appointed earlier this month to evaluate the proposal of its 80.4% stockholder
Vishay Intertechnology, Inc. (NYSE:VSH) to purchase the outstanding shares of
Siliconix it does not now own, has engaged the investment banking firm Lehman
Brothers Inc. and law firm of Heller Ehrman White & McAuliffe LLP as independent
advisors to assist the committee with its work. Vishay's proposed purchase price
is $28.82 per share payable in cash.

         The special committee consists of Mark B. Segall, Senior Vice President
and Director of Investment Banking of Investec Ernst & Company and Timothy V.
Talbert, Vice President of Credit and Origination of Lease Corporation of
America. As previously announced, the committee is authorized to communicate
directly with representatives of Vishay about the terms and conditions of
Vishay's proposal.

         Siliconix is a leading manufacturer of power MOSFETs, power IC and
analog signal processing devices for computers, cell phones, fixed
communications networks,



automobiles and other electronic systems. The company uses Class 1, six-inch
wafer fabs dedicated to the manufacture of power products in Santa Clara,
California and Itzehoe, Germany. Power products are also manufactured by a
subcontractor in Japan. Analog switches and multiplexers are fabricated by a
subcontractor in Dresden, Germany, and small-signal transistors are
manufactured by a subcontractor in Beijing, China. Assembly and test
facilities include a company-owned facility in Taiwan, a facility in
Shanghai, China, and subcontractors in the Philippines, China and the United
States.

         If Vishay proceeds with converting its proposal to a firm offer,
Siliconix will file a responsive solicitation/recommendation statement in
response to that offer with the Securities and Exchange Commission. Because that
document would contain important information, investors and security holders are
advised to read it if and when it becomes available. Investors and security
holders may obtain a free copy of the solicitation/recommendation statement (if
and when available) and other documents filed by Siliconix at the SEC's web site
www.sec.gov. They may also obtain the solicitation/recommendation statement and
the other documents (if and when available) free of charge from Siliconix by
directing a request to Siliconix incorporated, 2201 Laurelwood Road, Santa
Clara, California 95054, telephone 408/567-8400, Attention: Investor Relations.
