Vishay launched a miniature package type for its Trench MOS Barrier Schottky (TMBS) and planar Schottky rectifiers with the 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 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 feature voltage ratings up to 100 V and current power densities of 8 A to 12 A. The 16 planar Schottky rectifiers provide voltage ratings from 20 V to 100 V, and current power densities from 3 A to 10 A. The single- or dual-chip, surface-mount SMPC (TO-277A) package of these 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 upgrades to existing devices.
