Description/ Features
The 12TQ... Schottky rectifier series 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.
