FEATURES

• 150 °C TJ operation

• Center tap module

• Optimized for 3.3 V application

• Ultralow forward voltage drop

• High frequency operation

• Guard ring for enhanced ruggedness and long term
reliability

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

DESCRIPTION

The center tap Schottky rectifier module has been optimized
for ultralow forward voltage drop specifically for 3.3 V output
power supplies. The proprietary barrier technology allows for
reliable operation up to 150 °C junction temperature. Typical
applications are in parallel switching power supplies,
converters, reverse battery protection, and redundant power
subsystems.
