DESCRIPTION / APPLICATIONS

The VS-301CNQ... center tap Schottky rectifier module

series has been optimized for low reverse leakage at high

temperature. The proprietary barrier technology allows for

reliable operation up to 175 °C junction temperature. Typical

applications are in high current switching power supplies,

plating

power

supplies,

UPS

systems,

converters,

freewheeling

diodes,

welding,

and

reverse

battery

protection.
