| Preliminary Data Sheet PD-20575 11/98 48CTQ060L 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 60 1000 0.58 V A V Description/Features The 48CTQ060L 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 48CTQ...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 48CTQ060L Preliminary Data Sheet PD-20575 11/98 Voltage Ratings Part number VR Max.
