| STPS40L15CTPbF Vishay High Power Products Schottky Rectifier, 2 x 20 A FEATURES Base 2 common cathode * * * * * * Anode TO-220AB Anode 2 1 Common 3 cathode 125 C TJ operation (VR < 5 V) Center tap module Pb-free Available Optimized for OR-ing applications Ultra low forward voltage drop RoHS* COMPLIANT 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 * Lead (Pb)-free ("PbF" suffix) * Designed and qualified for industrial level DESCRIPTION PRODUCT SUMMARY IF(AV) VR IRM 2 x 20 A 15 V 600 mA at 100 C The center tap 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.
