Typical applications include ac/dc and dc-dc converters, reverse battery protection andOrin of multiple supply voltages. The Powermite s patented heat sink design offers the same thermal performance rating as an SMA while being 50% smaller in footprint area and less than 1 mm in overall height. The result is a unique, highly efficient Schottky rectifier in a space saving surface mount package.
