Characteristics 40L..CW Units Major Ratings and Characteristics Description/ Features 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 applica- tions are in switching power supplies. 150° C T J 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) IF(AV) Rectangular 40 A waveform VRRM 40 - 45 V IFSM @ tp = 5 μs sine 1240 A VF @ 20 Apk, TJ=125°C 0.42 V (per leg, Typical) TJ - 55 to 150 °C SCHOTTKY RECTIFIER 40L40CWPbF 40L45CWPbF Bulletin PD-20794 rev.
