Characteristics
95HQ015 Units
The 95HQ015 Schottky rectifier 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 100 C junction tempera-
ture. Typical applications are in parallel switching power
supplies, converters, reverse battery protection, and redun-
dant power subsystems.
