ABSTRACT:
A circuit arrangement for gate-controlling a MOS field-effect transistor (T.sub.o) comprises a discharge circuit (12) via which the charge stored in the gate-source capacitance (C.sub.GS) can be discharged according to a time constant, the value of which depends on the internal impedance of said discharge circuit (12). This discharge circuit (12) can be switched between two conditions determined by a relatively large and a relatively small internal impedance respectively and assumes the condition dictated by the relatively small internal impedance as soon as the gate-source voltage (U.sub.GS) has dropped below a predetermined limit.
