• Optimized for OR-ing applications
• Ultra low forward voltage drop
Pb-free
Available
RoHS*
COMPLIANT
• Guard ring for enhanced ruggedness and long term
reliability
• High purity, high temperature epoxy encapsulation for
enhanced mechanical strength and moisture resistance

• Designed and qualified for industrial level
DESCRIPTION
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.
