• Powermite is JEDEC Registered as DO-216AA
Case: Molded Epoxy
Epoxy Meets UL94, VO at 1/8"
Weight: 62 mg (appoximately)
Device Marking: S40
Lead and Mounting Surface Temperature for Soldering Purposes,
260°°C Maximum for 10 Seconds 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. Maximum Ratings
