| Bulletin PD-2259 rev. E 06/01 203CNQ...(R) SERIES SCHOTTKY RECTIFIER 200 Amp TO-244AB Major Ratings and Characteristics Characteristics IF(AV) Rectangular waveform VRRM range IFSM @ tp = 5 s sine VF TJ @ 100Apk, TJ=125C (per leg) range Description/ Features Units A V A V C The 203CNQ... (R) 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 high current switching power supplies, plating power supplies, UPS systems, converters, free-wheeling diodes, welding, 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 10.41 [.410] 9.65 [.380] Value 200 80 and 100 16,000 0.70 - 55 to 175 80.01 [3.150] 40.26 [1.585] 39.75 [1.565] COMMON CATHODE O 203CNQ100 Lug Terminal Anode 1 Lug Terminal Anode 2 20.32 [.800] 17.78 [.700] 2X O 7.49 [.295] 6.99 [.275] 34.925 [1.375] REF. 63.50 [2.500] 60.96 [2.400] O 4.95 [.195] 4.70 [.185] 1/4-20 SLOTTED HEX Base Common Cathode 203CNQ100(R) 23.55 [.927] 20.42 [.804] 15.75 [.620] 14.99 [.590] 3.35 [.132] 3.02 [.119] Cathode 1 Cathode 2 92.71 [3.650] 90.17 [3.550] NOTES: 1.
