Description/Features

ThecentertapSchottkyrectifiermodulehasbeenoptimizedfor 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
