POWER SCHOTTKY RECTIFIER

®

Single chip Schottky rectifier suited for Switch

Mode Power Supplies and high frequency DC to

DC converters.

Packaged in SMB, SMC and DPAK this device is

intended for use in low and medium voltage

operation, high frequency inverters, free wheeling

and polarity protection applications where low

switching losses are required.
