Abstract
Transistor and thyristor devices having paralleled main current paths are responsive to a control signal, for turning-on the transistor for conducting up to a predetermined limited magnitude of current, and the thyristor for conducting current of a magnitude greater than this limited magnitude. If the current reduces to below the predetermined limited magnitude, the thyristor turns off, and the transistor continues conducting current through its main current path down to a relatively low value of voltage thereacross.
