DCR490J65

The DCR490J65 is a kind of phase control thyristor. The typical applications include high power drives, high voltage power supplies and static switches. There are some features as follows: (1)double side cooling; (2)high surge capability.

The following is about the current ratings of DCR490J65 when Tcase=60 unless stated otherwise: (1)IT(AV), mean on-state current at half wave resistive load: 490 A; (2)IT(RMS), RMS value: 770 A; (3)IT, continuous (direct) on-state current: 730 A; (4)ITSM, surge (non-repetitive) on-state current at 10ms half sine, Tcase=125, VR=0: 6.6 kA; (5)I2t, I2t for fusing at 10ms half sine, Tcase=125, VR=0: 0.22 MA2s.

The last one is about the thermal and mechanical ratings of DCR490J65: (1)Rth(j-c), thermal resistance-junction to case for double side cooled: 0.0379 /W when DC; (2)Rth(j-c), thermal resistance-junction to case for single side cooled: 0.0745 /W when anode DC and 0.797 /W when cathode DC; (3)Rth(c-h), thermal resistance-case to heatsink: 0.0072 /W for double side and 0.0144 /W for single side; (4)Tvj, virtual junction temperature: 135 when on-state (conducting) and 125 when reverse (blocking); (5)Tstg, storage temperature range: -55 to +125.
