| PD - 2.536 11/97 151CNQ... SERIES SCHOTTKY RECTIFIER Major Ratings and Characteristics Characteristics IF(AV) Rectangular waveform VRRM range IFSM @ tp = 5 s sine VF TJ @ 75 Apk, T J = 125C (per leg) range 150 Amp Description/Features The 151CNQ... non-isolated, center tap Schottky rectifier module series has been optimized 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, freewheeling diodes, and reverse battery protection. 175 C TJ operation Center tap module Multiple leads per terminal for high frequency, high current PC board mounting 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 Low profile, high current package 151CNQ...
