201CNQ... Units
The 201CNQ 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, freewheeling diodes, welding, and reverse battery protection.
