DESCRIPTION

This center tap Schottky rectifier series has been optimized

for very low reverse leakage at high temperature. 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.
