Bulletin PD-20627 rev. C 06/06 STPS20L15D STPS20L15G SCHOTTKY RECTIFIER 20 Amps IF(AV) = 20Amp VR = 15V Major Ratings and Characteristics Description/Features 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.
