Description

Schottky rectifier suited for switch mode power
supply and high frequency DC to DC converters.

Packaged in PowerFLAT™, this device is
intended for use in low voltage, high frequency
inverters, free-wheeling and polarity protection
applications.

Its low profile was especially designed to be used
in applications with space-saving constraints.
