Devices feature high-current-density performance up to 100 V & 12 A

Vishay Electronic : 06 March, 2007  (New Product)
Vishay Intertechnology, Inc. launched a new miniature package type for its Trench MOS Barrier Schottky 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.
Vishay Intertechnology, Inc. launched a new miniature package type for its Trench MOS Barrier Schottky 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 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.
