| Preliminary Data Sheet PD-20572 11/98 40CTQ045L SCHOTTKY RECTIFIER 40 Amp TO-262 Major Ratings and Characteristics Characteristics IF(AV) Rectangular waveform VRRM IFSM @ tp = 5 s sine VF TJ @ 20 Apk, T J = 125C (per leg) range 45 1240 0.48 V A V Description/Features The 40CTQ045L center tap Schottky rectifier series has been optimized for very low forward voltage drop, with moderate leakage. The proprietary barrier technology allows for reliable operation up to 150C junction temperature. Typical applications are in switching power supplies, converters, freewheeling diodes, and reverse battery protection. 150 C TJ operation Center tap TO-262 package Low forward voltage drop High purity, high temperature epoxy encapsulation for enhanced mechanical strength and moisture resistance High frequency operation Guard ring for enhanced ruggedness and long term reliability 40CTQ...L Units 40 A - 55 to 150 C BASE COMMON CATHODE 2 1 2 3 ANODE COMMON ANODE CATHODE 1 2 Modified JEDEC outline TO-262 Dimensions in millimeters and inches www.irf.com 1 40CTQ045L Preliminary Data Sheet PD-20572 11/98 Voltage Ratings Part number VR Max.
