Press release date: October 10, 2007

New Devices Offered in PowerPAK® SC-70, SC-89, and Standard SC-70 MALVERN, Pa. - October 10, 2007 - A new family of p-channel MOSFETs that sets a new record for lowest on-resistance per unit area was announced today by Vishay Intertechnology, Inc. (NYSE: VSH).

Built on a new-generation TrenchFET® silicon technology, the new Vishay Siliconix devices offer maximum on-resistance ratings of 29 milliohms in the PowerPAK® SC-70 package (2.05 mm by 2.05 mm) and of 80 milliohms in the standard SC-70 (2.0 mm by 2.1 mm) and 130 milliohms in the SC-89 (1.6 mm by 1.6 mm).

Compared to the next-best power MOSFETs on the market, specifications for these new Vishay Siliconix devices represent an improvement of up to 63 %. The new p-channel TrenchFETs will be used for load switching, PA switching, and battery switching in portable end products including cell phones, MP3 players, PDAs, and digital still cameras, where their low conduction losses will help to extend battery run times and their miniaturized packages will save valuable board space, allowing increased functionality.

In portable electronic systems, p-channel MOSFETs perform an essential role by turning off features such as the display or the power amplifier when these are not being used, or by switching the system from active mode to sleep mode, and thus saving on battery life. These new Vishay Siliconix devices perform these switching tasks with less power than any previous p-channel power MOSFETs on the market since their very low on-resistance ratings translate directly into lower power conduction losses. The p-channel TrenchFETs released today include single-channel devices with breakdown voltage ratings of -12 V, -20 V, and -30 V. Offered in the 6-pin SC-89, standard SC-70, and PowerPAK® SC-70 packages, all are lead (Pb)-free to meet today.s environmental concerns.
