An exciter circuit for an externally excited synchronous machine, including voltage supply terminals for a voltage supply, exciter current terminals to be connected to an exciter winding of the synchronous machine, a bridge circuit hooked up to the voltage supply terminals, a controller and a protective layout at the side with the exciter current terminals, including: a semiconductor switch switched in series with the exciter winding, and in parallel with a protective diode which is blocking in an exciter current flow direction, and a cut-off voltage decay path running in parallel with the exciter winding and having a connection point between the bridge circuit and the semiconductor switch, having at least one Zener diode layout which is blocking in the exciter current flow direction, which defines a breakdown voltage and includes at least one Zener diode. The controller opens the semiconductor switch when a rapid de-exciting signal is present.
