Abstract
In a circuit configuration for the shutoff of a semiconductor component in the event of excess current, the semiconductor component has gate and cathode terminals and is controlled by the field effect. A controllable switch is connected between the gate and cathode terminals and is made conducting by a control signal. A device controls the controllable switch to a range of high on-state DC resistance when there is excess current and a shutoff signal is simultaneously present.
