Abstract

PURPOSE:To prevent transistors from breakdown through allowing current to flow from emitter to collector at turn-off time by incorporating operation stabilizing resistances without forming collector-emitter reverse parallel diode. CONSTITUTION:A drive stage transistor is made up of n type silicon substrate 1 and P type layer 2, n type layer 3 and an output stage transistor of the said substrate 1 and P type layer 2, n type layer 4; there are arranged a common base layer 2 and an n type layer 8 having resistance at another spot, around which is arranged a p type isolation layer 9 to isolate the n type layer 8 from substrate 1, and two electrodes 11, 12 given on the surface of this n type layer 8 are connected to base and emitter of the output stage transistor. This way of arrangement is capable of giving operation stabilizing resistances R3, R4 without forming a reverse parallel diode between collector and emitter, thus preventing transistors from breakdown at turn-off time as is so far the case therewith from the presence of reverse parallel diode.
