| Bulletin PD-20240 09/00 15CTQ... 15CTQ...S 15CTQ... -1 SCHOTTKY RECTIFIER 15 Amp IF(AV) = 15Amp VR = 35 to 45V Major Ratings and Characteristics Characteristics IF(AV) Rectangular waveform VRRM range IFSM @ tp = 5 s sine VF TJ @ 7.5 Apk, TJ = 125C (per leg) range Description/Features Units A The 15CTQ 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, free-wheeling diodes, and reverse battery protection. 175 C TJ operation Center tap TO-220 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 15CTQ 15 35 to 45 810 0.51 V A V - 55 to 150 C Case Styles 15CTQ... 15CTQ...S 15CTQ... -1 TO-220 D2PAK TO-262 www.irf.com 1 15CTQ...
