SANTA CLARA, CALIFORNIA - August 17, 2001 - Siliconix incorporated (NASDAQ: SILI), an 80.4%-owned subsidiary of Vishay Intertechnology, Inc. (NYSE: VSH), has reconfirmed its performance leadership in the power MOSFET arena with the release of two TrenchFETs® in the LITTLE FOOT® SO-8 with about half the on-resistance of the closest equivalent devices on the market.

Aimed at synchronous buck dc-to-dc converter applications, the new devices are rated for a maximum rDS(on) of just 3.5 mΩ for the Si4864DY and 3.3 mΩ for the Si4862DY. Either device can handle up to 25 A at a 4.5-V gate-to-source voltage. Maximum VDS for the Si4864DY is 20 V, while the Si4862DY is the industry's first power MOSFET with a 16-V drain-source voltage rating.

Used as the low-side synchronous MOSFET in dc-to-dc circuits, the new devices will enable the design of more efficient power converters in desktop computers, servers, and routers. The 20-V Si4864DY is intended for use in systems with 12-V power buses, while the Si4862DY, with its 16-V breakdown voltage, provides generous headroom in 5-V systems while eliminating the overkill - and on-resistance penalty - of using a 20-V MOSFET witha 5-V bus.

Samples and production quantities of the Si4862DY and Si4864DY are available now, with lead times of 8 to 10 weeks for larger orders.

Vishay Intertechnology, Inc., a Fortune 1000 Company listed on the NYSE (VSH), is one of the world's largest manufacturers of discrete semiconductors (diodes, MOSFETs, and infrared optoelectronics) and passive electronic components (resistors, inductors, and capacitors). These components are used in virtually all types of electronic devices and equipment, in the industrial, computing, automotive, consumer, telecommunications, military, aerospace, power supplies, and medical markets. Vishay’s product innovations, successful acquisition strategy, and "one-stop shop" service have made it a global industry leader. Vishay can be found on the Internet at www.vishay.com.
