FEATURES

• 125 °C TJ operation (VR < 5 V)

• Center tap module

• Optimized for OR-ing applications

• 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 ultra low forward voltage drop specifically for the OR-ing
of parallel power supplies. The proprietary barrier technology
allows for reliable operation up to 125 °C junction
temperature. Typical applications are in parallel switching
power supplies, converters, reverse battery protection, and
redundant power subsystems.
