A
The 30CTQ... center tap Schottky rectifier has been opti-
mized for very low forward voltage drop, with moderate
leakage. The proprietary barrier technology allows for reli-
able operation up to 175° C junction temperature. Typical
applications are in switching power supplies, converters,
free-wheeling diodes, and reverse battery protection.
