Bulletin PD-20862 10/04 8TQ...PbF Series 8 Amp SCHOTTKY RECTIFIER IF(AV) = 8 Amp VR = 80 - 100V Major Ratings and Characteristics Description/ Features Characteristics Values Units IF(AV) Rectangular 8 A 80 - 100 V waveform VRRM range IFSM @ tp = 5 s sine 850 A VF @ 8 Apk, TJ = 125C 0.58 V TJ range - 55 to 175 C The 8TQ...PbF Schottky rectifier series has been optimized for low reverse leakage at high temperature. The proprietary barrier technology allows for reliable operation up to 175 C junction temperature. Typical applications are in switching power supplies, converters, free-wheeling diodes, and reverse battery protection. 175 C TJ operation High purity, high temperature epoxy encapsulation for enhanced mechanical strength and moisture resistance Low forward voltage drop High frequency operation Guard ring for enhanced ruggedness and long term reliability Lead-Free ("PbF" suffix) Case Styles 8TQ...PbF Base Cathode 2 1 Cathode 3 Anode TO-220AC www.irf.com 1 8TQ...PbF Series Bulletin PD-20862 10/04 Voltage Ratings Part number VR 8TQ080PbF 8TQ100PbF 80 100 Max.
