Description/Features
The 95SQ015 axial leaded Schottky rectifier has been opti-
mized 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 100 C junction
temperature. Typical applications are in parallel switching
power supplies, converters, reverse battery protection, and
redundant power subsystems.

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
