| STPS20L15G Vishay High Power Products Schottky Rectifier, 20 A FEATURES Base cathode 2 1 D2PAK N/C 3 Anode 125 C TJ operation (VR < 5 V) Center tap module 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 * Designed and qualified for Q101 level * * * * * * DESCRIPTION PRODUCT SUMMARY IF(AV) VR IRM 20 A 15 V 600 mA at 100 C 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.
