Abstract
A monolithically integrated gate turn-off device is disclosed comprising a vertical power transistor collector-base connected with a lateral transistor to form a regenerative loop. The device is turned on by signal current of one polarity applied to the base of the power transistor driving the latter into conduction, and remains ON upon removal of the signal current due to base drive supplied by the collector of the other transistor in the regenerative loop. The device is turned OFF by signal current of opposite polarity breaking the regenerative loop.
