| Bulletin PD-2.175 05/00 161CNQ... SERIES SCHOTTKY RECTIFIER 160 Amp Major Ratings and Characteristics Characteristics IF(AV) Rectangular waveform VRRM range IFSM VF TJ @ tp = 5 s sine @ 80 Apk, TJ = 125C (per leg) range Description/Features TO-249AA 161CNQ... Units 160 35 to 45 11500 0.63 A V A V The 161CNQ non isolated, center tap Schottky rectifier module series has been optimized for very low forward voltage drop, with moderate leakage. The proprietary barrier technology allows for reliable operation up to 175 C junction temperature. T y p i c a l applications are in switching power supplies, converters, freewheeling diodes, and reverse battery protection. 175 C T J operation Isolated heatsink Center tap module 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 - 55 to 175 C (NON ISOLATED BASE) Outline TO-249AA Dimensions in millimeters and (inches) www.irf.com 1 161CNQ...
