• 125 °C TJ operation (VR < 5 V)

• Center tap module

• Optimized for OR-ing applications

• Ultra 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

DESCRIPTION

The STPS40L15CWPbF 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.
