Abstract
The invention relates to an integrated transistor circuit comprising a transistor (Q1) of which the collector is connected to an input of a circuit (S) and between the base and collector of which an antisaturation diode (D1) is connected. According to the invention a further current branch is provided between the base and the emitter and includes a series circuit of a diode (D2) and a resistor (R1). As a result, a leakage current flowing in reverse direction into the antisaturation diode (D1) flows via the diode (D2) and the resistor (R1) and not via the emitter-base path of the transistor (Q1) and consequently amplification of the leakage current is prevented.
