ABSTRACT:
A circuit arrangement includes a first semiconductor switch and at least one second semiconductor switch, each of them having a control terminal and a first and second load terminal, and with an overvoltage protection arrangement for the at least two semiconductor switches. The overvoltage protection arrangement comprises a voltage limiting unit with a first and a second terminal, whose first terminal is connected to a central circuit node, whose second terminal is connected to a terminal for a reference potential, and which is configured so that it conducts current when a threshold voltage is applied between the first and second load terminals. The central circuit node is coupled to the first load terminals of the semiconductor switches. The overvoltage protection arrangement further comprises a first actuating circuit for the first semiconductor switch and a second actuating circuit for the at least one second semiconductor switch.
