Abstract

Embodiments relate to a device and method for protecting an electrical system component of a vehicle electrical system. The device comprises a semiconductor switch connected to the electrical system component. A circuit connected to the semiconductor switch comprises a detection unit for detecting an electrical malfunction of the vehicle electrical system and an activation unit for activating the semiconductor switch. A control unit communicatively connected to the circuit is configured to switch the semiconductor switch into a first safe state, in which the semiconductor switch is switched off, based on the detection of an electrical malfunction, and to selectively switch the semiconductor switch into the first safe state or into a second safe state, in which the semiconductor switch is switched on, based on at least one predetermined vehicle state.
