| Bulletin PD-20844 09/04 20L15TPBF SCHOTTKY RECTIFIER 20 Amps IF(AV) = 20Amp VR = 15V Major Ratings and Characteristics Characteristics IF(AV) Rectangular waveform VRRM IFSM @ tp = 5 s sine VF TJ @ 19 Apk, TJ=125C ( Typical) range - 55 to 125 C 15 700 0.25 V A V Description/ Features Units A 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. 125C TJ 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 Lead-Free ("PbF" suffix) Values 20 Case Styles 20L15TPBF Base Cathode 2 1 3 Cathode Anode TO-220AC www.irf.com 1 20L15TPBF Bulletin PD-20844 09/04 Voltage Ratings Part number VR Max.
