| PD-2.248 rev. A 12/97 61CNQ... SERIES SCHOTTKY RECTIFIER 60 Amp Major Ratings and Characteristics Characteristics IF(AV) Rectangular waveform VRRM IFSM @ tp = 5 s sine VF TJ @ 30 Apk, T J = 125C (per leg) 35 to 45 6300 0.49 V A V Description/Features Units A The 61CNQ center tap Schottky rectifier module 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 TJ operation Center tap module High purity, high temperature epoxy encapsulation for enhanced mechanical strength and moisture resistance Low forward voltage drop High frequency operation Guard ring for enhanced ruggedness and long term reliability Low profile, small footprint, high current package 61CNQ... 60 - 55 to 175 C CASE STYLE AND DIMENSIONS Outline D - 61 - 6 Dimensions in millimeters and inches www.irf.com 1 61CNQ...
