Characteristics 40L45CW Units Major Ratings and Characteristics Description/Features The 40L45CW center tap Schottky rectifier has been opti- mized 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 Dimensions in millimeters and inches Conform to JEDEC outline TO-247AC (TO-3P) BA SE COMMON CATHODE 12 3 ANODECOMMON CATHODE ANODE 15 . 90 (0 .6 26 ) 15 . 30 (0 .6 02 ) 14 . 20 (0.5 59 ) 14.80 (0.5 83) 3.70 (0.1 4 5) 4.30 (0.170) 5. 30 (0. 208) 5.70 (0 . 22 5) 5. 50 (0. 217) 4.50 (0 . 17 7) (2 P L CS .) 3. 5 5 (0 .1 3 9 ) 3.65 (0 . 14 4) 2.20 (0 . 08 7) MA X. 1. 0 0 (0 . 03 9 ) 1. 4 0 (0 . 05 6 ) 0. 4 0 (0 .2 1 3 ) 0.80 (0. 032) 4. 70 (0.18 5) 5.30 (0.209) 1. 5 (0.05 9) 2. 5 (0 .098) 2. 4 0 (0 . 09 5 ) MAX. 10.86 (0 . 427 ) 10.94 (0. 430) 20 . 30 (0.800) 19 . 70 (0.775) DIA. 12 3 TO-247AC IF(AV) Rectangular 40 A waveform VRRM 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 40L45CW PD-20566 rev.
