SCHOTTKY RECTIFIER 30 Amp
IF(AV) = 30Amp VR = 35 to 45V
Major Ratings and Characteristics Characteristics
IF(AV) Rectangular waveform VRRM range IFSM @ tp = 5 s sine VF TJ @ 15 Apk, TJ=125C (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
