ABSTRACT:
A power semiconductor component assembly includes a power semiconductor component having a semiconductor body. A controllable switch is connected to the power semiconductor component. A temperature sensor has a given reset time. The temperature sensor is connected to the controllable switch for turning on the controllable switch to control the power semiconductor component from a conducting state into a range of higher resistance once a temperature in the semiconductor body of the power semiconductor component attains a critical value. A delay member is connected between the temperature sensor and the controllable switch. The delay member is triggered upon response of the temperature sensor and has a delay time being longer than the given reset time, for preventing blocking of the controllable switch during the delay time.
