Description/Features
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 opera-
tion up to 175° C junction temperature. Typical applications
are in high current switching power supplies, converters, free-
wheeling diodes, welding, and reverse battery protection.
175° C TJ operation
Center tap module
High purity, high temperature epoxy encapsulation for
enhanced mechanical strength and moisture resistance
Low forward voltage drop
High frequency operation
Guard ring for enhanced ruggedness and long term
reliability
