Description/Features
The 409CNQ 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, plating power supplies,
UPS systems, 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
