Description/Features
The 124NQ... (R) high current Schottky rectifier modules have
been optimized for extremely low forward voltage drop, with
higher leakage. The proprietary barrier technology allows for
reliable operation up to 125° C junction temperature. Typical
applications are in switching power supplies, converters, free-
wheeling diodes, welding, and reverse battery protection.
