New ultrafast and power Schottky diodes deliver high power in 1.1 mm high, extra-slim package

Housed in an extra-slim PSMC package (TO-277A) able to withstand very high operating junction temperatures, this new ultrafast and Schottky diode series minimizes the PCB footprint while bringing the best of thermal efficiency.
In addition to having a low forward voltage drop and avalanche capability, these ultrafast and Schottky barrier rectifiers, which are rated from 30 to 200 V with a current rating from 5 to 12 A, help ensure greater compactness of equipment, with increased power density and efficiency, in a large range of applications including car modules, industrial equipment, telecom power systems and personal electronics.
