C 07/06 Major Ratings and Characteristics IF(AV) Rectangular 20 A waveform VRRM range 35 / 45 V IFSM @ tp = 5 μs sine 1060 A VF @ 10 Apk, TJ = 125°C 0.57 V (per leg) TJ range - 55 to 175 °C Characteristics Values Units Description/Features The 20CTQ center tap Schottky rectifier series has been optimized for low reverse leakage at high temperature. The proprietary barrier technology allows for reliable operation up to 175° C junction temperature. Typical applications are in switching power supplies, converters, free-wheeling diodes, and reverse battery protection. 175° C T J 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 IF(AV) = 20Amp VR = 35/ 45V Case Styles TO-220 D 2PAK Anode 1 3 Base Common Cathode Anode Common Cathode TO-262 Anode 1 3 Base Common Cathode Anode Common Cathode Anode 1 3 Base Common Cathode Anode Common Cathode
