DESCRIPTION
This 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 150 °C junction temperature. Typical
applications are in switching power supplies, freewheeling
diodes, and reverse battery protection.
