| Bulletin PD-20.758 rev. A 03/02 111CNQ045A SCHOTTKY RECTIFIER New GenIII D-61 Package Major Ratings and Characteristics Characteristics IF(AV) Rectangular waveform VRRM IFSM @ tp = 5 s sine VF TJ @55 Apk, TJ = 125 C (per leg) range 110 Amp Description/Features The 111CNQ045A center tap Schottky rectifier module 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. Typical applications are in switching power supplies, converters, freewheeling diodes, and reverse battery protection. 175 C TJ operation Center tap module Very 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 Low profile, small footprint, high current package 111CNQ045A Units 110 45 4000 0.55 A V A V - 55 to 175 C New fully transfer-mold low profile, small footprint, high current package Case Styles 111CNQ045A 111CNQ045ASM 111CNQ045ASL D61-8 www.irf.com D61-8-SM D61-8-SL 1 111CNQ045A Bulletin PD-20.758 rev.
