A surge protection circuit, method, computer readable medium, and use, including: at least one first electronic component having a non-linear characteristic, electrically conductively connected between a tapping point, to which a supply potential is appliable, and a node point; at least one second electronic component having a non-linear characteristic, electrically conductively connected between a tapping point, to which a ground potential is appliable, and the node point; a resistor connected between the node point and a control connection; and a monitoring unit to apply a predetermined voltage to the control connection or to output a predetermined current via the control connection and to detect a voltage/potential at the node point in response thereto, the monitoring unit being configured to identify a malfunction in the surge protection circuit when the detected voltage or the detected potential is not related to an expected voltage or expected potential in a predetermined manner. |
