Description/Features
Major Ratings and Characteristics
Characteristics
The 95SQ015 axial leaded Schottky rectifier has been optimized for ultra low forward voltage drop specifically for the ORing 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
redundantpower subsystems.
