SCHOTTKY RECTIFIER
30 Amp
Bulletin PD-20626 rev. B 02/03
1
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 150 C junction temperature. Typical applications are
in switching power supplies, converters, free-wheeling
diodes, and reverse battery protection.
