Description
This Schottky rectifier is designed 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, by-pass diode and polarity protection
applications.Its low profile was especially designed to be used in applications with
space-saving constraints.
