Description/Features
The 83CNQ...A 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 switching power supplies, converters, freewheeling diodes, 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
New fully transfer-mold low profile, small
footprint, high current package
