Abstract

PURPOSE:To obtain a high dv/dt insulation resistance, by providing a control emitter of the same conducting type as an N emitter along a ring gate on the side not facing an N emitter of the ring gate. CONSTITUTION:On the side not facing N emitter 8 of ring gate electrode 3, ring- shaped control emitter 11 having the same conducting type as N emitter 8 is formed along ring gate electrode 3. By this control emitter 11, it is made possible to adjust resistor R2 in P base 7 between ring gate electrode 3 and ring 4 and to check the increase of the gate current not contributing to the firing of the main SCR. By this, the firing current of the main SCR can be reduced and at the same time a high dv/dt insulation resistance can be obtained.
