DESCRIPTION
This center tap Schottky rectifier has been optimized for
very low forward voltage drop, with moderate leakage. The
proprietary barrier technology allows for reliable operation
up to 125 °C junction temperature. Typical applications are
in switching power supplies, converters, freewheeling
diodes, and reverse battery protection.
