Description/Features
The 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)
Single diode configuration
Optimized for OR-ing applications
Ultra low forward voltage drop
Guard ring for enhanced ruggedness and long term
reliability
High purity, high temperature epoxy encapsulation for
enhanced mechanical strength and moisture resistance
