This center tap Schottky rrectifier 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, converters, free-wheeling
diodes, and reverse battery protection.
