FEATURES

• 150 °C TJ operation

• Center tap module

• Very low forward voltage drop

• High frequency operation

• High purity, high temperature epoxy encapsulation for
enhanced mechanical strength and moisture resistance

• Guard ring for enhanced ruggedness and long term
reliability

• New fully transfer-mold low profile, small footprint, high
current package

• Designed and qualified for industrial level

DESCRIPTION

The 112CNQ030A 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, freewheeling diodes, and reverse battery
protection.
