Gate turn-off device with high turn-off gain |
摘要 |
A gate turn-off device is disclosed having a load current carrying power transistor regeneratively collector-base coupled with another transistor, and includes a third, shunting transistor providing high gain turn-off. The device is turned ON by signal current of one polarity applied to the base of the power transistor driving the latter into conduction to carry load current, and the device remains ON upon removal of the signal due to base drive supplied by the collector of the other transistor in the regenerative loop. A third transistor is connected to one of the collector-base junctions to shuntingly break the regenerative loop when the third transistor is biased into conduction, thus providing higher gain turn-off. A single ON-OFF control terminal is disclosed, as well as separate ON and OFF control terminals.
