| Bulletin PD-20550 rev. B 08/03 322CNQ030 SCHOTTKY RECTIFIER 300 Amp Major Ratings and Characteristics Characteristics IF(AV) Rectangular waveform VRRM IFSM @ tp = 5 s sine VF TJ @150 Apk, TJ = 125C (per leg) range Description/ Features The 322CNQ030 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 150 C junction temperature. Typical applications are in switching power supplies, converters, free-wheeling diodes, and reverse battery protection. 150 C TJ operation High Surge Capability 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, high current package 322CNQ030 Units 300 30 10000 0.49 A V A V - 55 to 150 C CASE STYLE AND DIMENSIONS * PRE-SOLDER CHIP DIMENSIONS Outline D-60 (Modified JEDEC TO-249AA) Dimensions in millimeters and inches www.irf.com 1 322CNQ030 Bulletin PD-20550 rev.
