| Bulletin PD-20624 05/01 STPS40L40CW SCHOTTKY RECTIFIER 40 Amp Major Ratings and Characteristics Characteristics IF(AV) Rectangular waveform VRRM IFSM @ tp = 5 s sine VF TJ @ 20 Apk, TJ=125C (per leg) Description/Features Units A V A V TO-247AC Value 40 40 3500 0.43 The STPS40L40CW 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, converters, free-wheeling diodes, and reverse battery protection. 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 - 55 to 150 C 15 .90 (0 .626 ) 15 .30 (0 .602 ) 3. 65 (0 .14 4) 3. 55 (0 .13 9) DIA. 5. 30 (0 .20 9) 4.70 ( 0.185) 2.5 ( 0.098) 1.5 ( 0.059) 5. 70 (0 .22 5) 5.30 ( 0.208) 20 .30 (0 .800 ) 19 .70 (0 .775 ) 5.50 ( 0.217) 4. 50 (0 .17 7) 1 2 3 (2 PLCS.) 1 2 3 ANODE 2 BASE COMMON CATHODE 2 14. 80 ( 0.583) 14 .20 (0 .559 ) ANODE COMMON CATHODE 1 4. 30 (0 .17 0) 3. 70 (0 .14 5) 2. 20 (0 .08 7) 1. 40 (0 .05 6) 2. 40 (0 .09 5) MAX. 0.80 ( 0.032) 0. 40 (0 .21 3) MAX. 1. 00 (0 .03 9) 10. 94 ( 0.430) 10 .86 (0 .427 ) Conform to JEDEC outline TO-247AC (TO-3P) Dimensions in millimeters and inches 1 www.irf.com STPS40L40CW Bulletin PD-20624 05/01 Voltage Ratings Part number VR Max.
