SCHOTTKY RECTIFIER 20 Amps 20L15T 20L15TS Bulletin PD-20577 rev. D 08/01 1www.irf.com IF(AV) Rectangular 20 A waveform VRRM 15 V IFSM @ tp = 5 µs sine 700 A VF @ 19 Apk, TJ=125°C 0.25 V ( Typical) TJ range - 55 to 125 °C Characteristics Values Units Major Ratings and Characteristics 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 T J operation (VR < 5V) Single diode configuration Optimized for OR-ing applications Ultra low forward voltage drop Guard ring for enhanced ruggedness and long term reliability High purity, high temperature epoxy encapsulation for enhanced mechanical strength and moisture resistance Description/Features 20L15T Case Styles TO-220AC D 2PAK 20L15TS Anode 1 3 C athode Base Cathode Anode 1 3 Base Cathode N /C
