SH400R28B

The SH400R28B is designed as one kind of toshiba alloy-free high speed thyristors for high power control applications.

SH400R28B has eight features. (1)Repetitive peak off-state voltage is 1300V. (2)Its repetitive peak reverse voltage would be 1300V. (3)Its average on-state current is 400A. (4)Its turn-off time would be 25us max. (5)Its critical rate of rise of on-state current would be 200A/us. (6)Its critical rate of rise of off-state voltage would be 500V/us. (7)Its weight is 480g. (8)Flat package. Those are all the main features.

Some absolute maximum ratings of SH400R28B have been concluded into several points as follow. (1)Its repetitive peak off-state voltage and repetitive peak reverse voltage would be 1300V. (2)Its non-repetitive peak reverse voltage would be 1400V. (3)Its RMS on-state current would be 630A. (4)Its average on-state current would be 400A. (5)Its peak one cycle surge on-state current non repetitive would be 7200A for 50Hz and 8000A for 60Hz. (6)Its I2t limit value would be 200000A2s. (7)Its critical rate of rise of on-state current would be 200A/us. (8)Its peak gate power dissipation would be 20W. (9)Its average gate power dissipation would be 4W. (10)Its peak forward gate current would be 4A. (11)Its peak forward gate voltage would be 20V. (12)Its peak reverse gate voltage would be 5V. (13)Its junction temperature range would be from -40°C to 115°C. (14)Its storage temperature range would be from -40°C to 115°C. (15)Its mounting force would be 14.7+/-1.5kN. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of SH400R28B are concluded as follow. (1)Its repetitive peak off-state current and repetitive peak reverse current would be max 50mA. (2)Its peak on-state voltage would be max 2.2V. (3)Its gate trigger voltage would be max 3.5V. (4)Its gate trigger current would be 260mA. (5)Its gate non-trigger voltage would be min 0.2V. (6)Its gate non-trigger current would be min 5mA. And so on. If you have any question or suggestion or want to know more information of SH400R28B, please contact us for details. Thank you!
