SCHOTTKY RECTIFIER Bulletin PD-20240 rev. B 07/06 15CTQ... 15CTQ...S 15CTQ... -1 15 Amp IF(AV) = 15Amp VR = 35/ 45V Major Ratings and Characteristics Characteristics Values Units IF(AV) Rectangular waveform 15 A VRRM range 35 / 45 V IFSM @ tp = 5 μs sine 810 A VF @7.5 Apk, TJ = 125°C 0.51 V (per leg) TJ range - 55 to 150 °C Description/Features 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 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-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...
