トランジスタ回路。 In a transistor circuit comprising a drive transistor through which a drive current flows in response to a control input signal and a main transistor conductive by the drive current, a base current of the main transistor charges between the bases of the drive transistor and the main transistor. capacitance means connected across the emitter of the main transistor and the capacitance means, and is turned on when the drive transistor is turned off, transferring the charge of the capacitance means to the base-emitter path of the main transistor. A switching transistor circuit comprising a discharge transistor that discharges a discharge.
