Abstract
A vehicle on-board electric power system is disclosed including at least one field-effect-controlled power transistor which applies a vehicle on-board electric power system supply voltage Vto a load when actuated by a logic circuit. The power transistor has a drain-source breakdown voltage Vwith a positive temperature coefficient TKand is provided with a clamping means for protecting against overvoltages Voccurring in the vehicle on-board electric power system. The clamping means has a clamping voltage Vwith a positive temperature coefficient TK≈TK, the clamping voltage Vbeing lower than or equal to an anticipated maximum overvoltage Vin the vehicle on-board electric power system.
