Description/ Features
The STPS40L15CW 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.
125°C TJ operation (VR < 5V)
Center tap module
Optimized for OR-ing applications
Ultra low 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
