The 19TQ015.. 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 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)
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
