| PD-20566 rev. A 11/99 40L45CW SCHOTTKY RECTIFIER 2 x 20 Amps TO-247AC Major Ratings and Characteristics Characteristics IF(AV) Rectangular waveform VRRM IFSM @ tp = 5 s sine VF TJ @ 20 Apk, TJ=125C (per leg, Typical) - 55 to 150 C Description/Features The 40L45CW 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 40L45CW Units 40 45 1240 0.42 A V A V 3 . 6 5 ( 0 .1 4 4 ) 1 5 .9 0 ( 0 . 62 6 ) 1 5 .3 0 ( 0 . 60 2 ) 5 . 7 0 ( 0 .2 2 5 ) 5 .3 0 ( 0 .2 0 8 ) 2 0 .3 0 ( 0 . 8 0 0 ) 1 9 .7 0 ( 0 . 7 7 5 ) 5 .5 0 ( 0 .2 1 7 ) 4 . 5 0 ( 0 .1 7 7 ) ( 2 P L C S .) 3. 5 5 ( 0 .1 3 9 ) D IA. 5.30 (0.209) 4 .7 0 ( 0 . 1 85 ) 2 .5 ( 0. 0 9 8 ) 1 .5 ( 0 . 0 5 9 ) BASE COMMON CATHODE 2 1 2 3 1 2 3 1 4 . 8 0 ( 0 . 58 3 ) 1 4 .2 0 ( 0 . 5 5 9 ) ANODE COMMON ANODE CATHODE 1 2 4.30 (0.170) 3 . 7 0 ( 0 . 14 5 ) 2 . 2 0 ( 0 .0 8 7 ) M AX . 0 . 8 0 ( 0 .0 3 2 ) 0. 4 0 ( 0 .2 1 3 ) 2 . 40 ( 0 .0 9 5) M AX . 1 . 4 0 ( 0 .0 5 6 ) 1 . 00 ( 0 .0 3 9) 1 0 . 9 4 ( 0 .4 3 0 ) 1 0 . 8 6 ( 0 .4 2 7 ) Conform to JEDEC outline TO-247AC (TO-3P) Dimensions in millimeters and inches 40L45CW PD-20566 rev.
