SCHOTTKY RECTIFIER Bulletin PD-2.264 rev. D 05/02 400CNQ... SERIES 400 Amp Major Ratings and Characteristics Characteristics 400CNQ... Units IF(AV) Rectangular waveform VRRM range 400 35 to 50 IFSM @ tp = 5 µs sine 29,000 VF @200Apk, TJ=125°C (per leg) 0.52 TJ range - 55 to 150 A V A V °C TO-244AB Description/ Features The 400CNQ center tap, high current, 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 150 °C junction temperature. Typical applications are in switching power supplies, converters, free-wheeling diodes, welding, and reverse battery protection. 150 °C TJ operation 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 COMMON CATHODE 80.01 [3.150] 40.26 [1.585] 39.75 [1.565] 2X Ø 7.49 [.295] 6.99 [.275] 23.55 [.927] 20.42 [.804] 34.925 [1.375] REF. 63.50 [2.500] 60.96 [2.400] 92.71 [3.650] 90.17 [3.550] NOTES: 1.
