Product Name: Schottky rectifiers offered in mini SMPC package
Product Description
Malvern, Pa. — Vishay Intertechnology, Inc. has launched a new miniature SMPC package 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. Housed in a 4.8 x 6.7 x 1.1-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 industrial systems; and OR-ing diodes for telecommunication and industrial systems.
The three TMBS rectifiers in the SMPC package 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, said the company.
The single- or dual-chip, surface-mount SMPC (TO-277A) package features solder pads that are compatible with other SMD devices, so no modification is needed to the printed-circuit-board (PCB) layout when they are used as higher-performing upgrades to existing devices.
Pricing for U.S. delivery is $0.25 each in quantities of 1000 for the SS10P4. Samples and production quantities of the SMPC-packaged rectifiers are available now with lead times of six to eight weeks for immediate orders.
