Description/Features
The 82CNQ030A 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 150 °C junction temperature.
Typical applications are in switching power supplies, converters, free-wheeling diodes, and reverse battery protection.
150 °C TJ operation
Dual center tap module
Very low forward voltage drop
High purity, high temperature epoxy encapsulation for
enhanced mechanical strength and moisture resistance
High frequency operation
Guard ring for enhanced ruggedness and long term
reliability
New fully transfer-mold low profile, small
footprint, high current package
