Description/ Features

The 12CTQ center tap Schottky rectifier series has been

optimized for low reverse leakage at high temperature. The

proprietary barrier technology allows for reliable operation up

to 175° C junction temperature. Typical applications are in

switching power supplies, converters, free-wheeling diodes,

and reverse battery protection.
