Description:

Description:

The UPS140 Powermite Schottky rectifier is designed to offer optimized forward voltage 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.
