A 06/06 25CTQ...SPbF 25CTQ.. -1PbF SCHOTTKY RECTIFIER 30 Amp IF(AV) = 30Amp VR = 35/ 45V Major Ratings and Characteristics Characteristics IF(AV) Rectangular waveform VRRM range IFSM @ tp = 5 μs sine VF TJ @ 15 Apk, TJ=125°C (per leg) range Description/ Features Units A The 25CTQ.. 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 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 Lead-Free ("PbF" suffix) Values 30 35/ 45 990 0.50 V A V - 55 to 150 °C Case Styles 25CTQ...SPbF 25CTQ...-1PbF Base Common Cathode 2 Base Common Cathode 2 1 Anode 2 Common Cathode 3 1 Anode Anode 2 Common Cathode 3 Anode D2PAK www.irf.com TO-262 1 25CTQ...SPbF, 25CTQ...-1PbF Series Bulletin PD-21032 rev.
