Description:
The UPS120E Powermite Schottky rectifier is designed to offer optimized reverse leakage characteristics for
battery powered portable products such as cellular and cordless phones, chargers, notebook computers,
printers, PDA's and PCMCIA cards. Typical applications include ac/dc and dc-dc converters, reverse battery
protection and "Oring" 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.
