Vishay's 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 100V and 12A in a space saving 4.8mm by 6.7mm 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/DC and DC/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 100V and high current power densities of 8A to 12A. The 16 planar Schottky rectifiers provide voltage ratings from 20V to 100V, and high current power densities from 3A to 10A. 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.
