Description/Features
The 89CNQ...A center tap Schottky rectifier module has been
optimized for very low forward voltage drop, with moderate
leakage. The proprietary barrier technology allows for reliable
operation up to 175°C junction temperature. Typical
applications are in switching power supplies, converters, free
wheeling 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
