Vishay Siliconix Extends Family of N-Channel TrenchFET(R) Power MOSFETs in Compact PowerPAK(R) SC-75 Package to Offer 8-V to 30-V VDS Range

MALVERN, PA--(Marketwire - August 14, 2009) - Vishay Intertechnology, Inc. (NYSE: VSH) today
expanded its family of n-channel TrenchFET® power MOSFETs in the
thermally enhanced PowerPAK® SC-75 package to offer a VDS range from 8 V
to 30 V. The devices released today include the industry's first 30-V
device in the 1.6-mm by 1.6-mm footprint area, and a 20-V MOSFET with the
industry's lowest on-resistance.

The new 30-V SiB408DK and 20-V SiB412DK join the previously released
Siliconix SiB414DK, the first 8-V single n-channel power MOSFET in the
PowerPAK SC-75 footprint area. On-resistance for the SiB408DK is as low as
40 milliohms at 10 V, while the SiB412DK offers an on-resistance down to 34
milliohms at 4.5 V, which is 21 % lower than the closest competing device.

The PowerPAK SC-75 package measures 1.6 mm by 1.6 mm by 0.8 mm. This is
36 % smaller than 2-mm by 2-mm devices and 72 % smaller than widely used
TSOP-6 devices, while offering similar on-resistance. For designers, the
smaller size of the PowerPAK SC-75 saves space and reduces power
consumption in portable electronics, allowing for increased functionality
while meeting consumer expectations for battery run times.

Typical applications for the n-channel PowerPAK SC-75 power MOSFETs will
include load, PA, and battery switches in portable electronics. The devices
will also save space in 1/8th or 1/16th bricks compared to common 3-mm by
3-mm packages. The SiB408DK will also be used for load switching in
notebook computers and netbooks.

The devices are halogen-free in accordance with IEC 61249-2-21 and are
compliant with RoHS Directive 2002/95/EC. The MOSFETs are 100 % Rg and UIS
tested.

Samples and production quantities of the new n-channel PowerPAK SC-75 power
MOSFETs are available now, with lead times of 10 to 12 weeks for larger
orders.
