A 11/06 40L40CWPbF 40L45CWPBF SCHOTTKY RECTIFIER 2 x 20 Amps IF(AV) = 40Amp VR = 40-45V Major Ratings and Characteristics Characteristics IF(AV) Rectangular waveform VRRM IFSM @ tp = 5 s sine VF TJ @ 20 Apk, TJ=125C (per leg, Typical) Description/ Features Units A The 40L..CWPbF center tap Schottky rectifier has been optimized for very low forward voltage drop, with moderate leakage. The proprietary barrier technology allows for reliable operation up to 150 C junction temperature. Typical applications are in switching power supplies. 150 C TJ operation Center tap TO-247 package High purity, high temperature epoxy encapsulation for enhanced mechanical strength and moisture resistance Very low forward voltage drop High frequency operation Guard ring for enhanced ruggedness and long term reliability Lead-Free ("PbF" suffix) 40L..CW 40 40 - 45 1240 0.42 V A V - 55 to 150 C Case Styles Base Common Cathode 2 1 3 2 Anode 1 Anode 2 Common Cathode TO-247AC www.irf.com 1 40L45CWPBF revA.pmd 1 21-Nov-06, 11:05 40L40CWPbF, 40L45CWPBF Bulletin PD-20794 rev.
