Description/Features
The 401CNQ center tap Schottky rectifier module 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 high
current switching power supplies, converters, free-wheeling
diodes, welding and reverse battery protection.
