SL3500LX21

The SL3500LX21 is a kind of alloy-free light trigger thyristor. The device is intended for high power control applications. There are some features as follows:(1)repetitive peak off-state voltage: VDRM=8000V; (2)repetitive peak reverse voltage: VRRM=8000V; (3)average on-state current: IT(AV)=3500A; (4)light trigger power: PLT=8mW(Max.); (5)turn-off time:tq=400s(Max.); (6)critical rate of rise of on-state current: dv/dt=200A/s; (7)critical rate of rise of off-state voltage:dv/dt=2300V/s; (8)flat package.

The following is about the SL3500LX21 absolute maximum ratings: (1)repetitive peak off-state voltage, VDRM: 8000 V; (2)repetitive peak reverse voltage, VRRM: 8800 V; (3)non-repetitive peak reverse voltage, VRSM (non-repetitive5 ms, Tj=0 to 115): 8800 V; (4)RMS on-state current, IT(RMS): 5498 A; (5)average on-state current, IT(AV): 3500 A; (6)peak one cycle surge on-state current (non-repetitive): ITSM: 60000 A (50 Hz) and 65000 A (60 Hz); (7)critical rate of rise of on-state current, di/dt: 200 A/s; (8)junction temperature, Tj: -40 to 120; (9)storage temperature, Tstg: -40 to 120.
