DESCRIPTION

Base

common

cathode

The 111CNQ045A center tap Schottky rectifier module has

been optimized for very low forward voltage drop, with

moderate leakage. The proprietary barrier technology allows

for reliable operation up to 175 °C junction temperature.

Typical applications are in switching power supplies,

converters, freewheeling diodes, and reverse battery

protection.
