C 06/06 STPS20L15D STPS20L15G SCHOTTKY RECTIFIER 20 Amps IF(AV) = 20Amp VR = 15V Major Ratings and Characteristics Characteristics IF(AV) Rectangular waveform VRRM IFSM @ tp = 5 μs sine VF TJ @ 19 Apk, TJ=125°C ( Typical) range Description/Features Units A V A V 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. 125°C TJ operation (VR < 5V) 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 Values 20 15 700 0.25 - 55 to 125 °C Case Styles STPS20L15D STPS20L15G Base Cathode Base Cathode 2 1 3 1 3 Cathode Anode N/C Anode TO-220AC www.irf.com D2PAK 1 STPS20L15D, STPS20L15G Bulletin PD-20626 rev.
