Vishay Releases TMBS™ and Planar Schottky Rectifiers in New SMPC Miniature Power Package

Devices Feature High-Current-Density Performance up to 100 V and 12 A in Space-Saving 4.8-mm by 6.7-mm Footprint

MALVERN, PENNSYLVANIA. — November 29, 2006 — Vishay Intertechnology, Inc. (NYSE: VSH) today launched a new miniature package type for its Trench MOS Barrier Schottky (TMBS™) and planar Schottky rectifiers that enables higher-current-density power supply designs with its compact dimensions and ability to handle up to 100 V and 12 A.

With a 1.1-mm height and 4.8-mm by 6.7-mm footprint, the new devices in the SMPC package are designed to provide more power in a smaller space for applications including secondary rectifiers and freewheeling circuitry for ac-to-dc and dc-to-dc converters; output rectification for small and medium power adaptors; switchmode power supplies in consumer electronics such as computers, LCD monitors, and cell phones; flywheel and polarity protection for solenoid drive circuits in automotive and industry systems; and OR-ing diodes for telecommunication and industrial systems.

The three TMBS rectifiers in the SMPC package released today feature voltage ratings up to 100 V and high current power densities of 8 A to 12 A. The 16 new planar Schottky rectifiers provide voltage ratings from 20 V to 100 V, and high current power densities from 3 A to 10 A. All the devices feature a very low forward voltage drop, and special wide-bottom plate designs that provide greater heat dissipation than other packages of similar sizes.

The single- or dual-chip, surface-mount SMPC (TO-277A) package of these new rectifiers features solder pads that are compatible with other SMD devices, so no modification is needed to the PCB layout when they are used as higher-performing upgrades to existing devices.
