Abstract
A protective device for a voltage-controlled semiconductor switch has a gate connection, a power emitter connection, an auxiliary emitter connection and a collector connection. The semiconductor switch can switch a current between the collector connection and the power emitter connection. A voltage-limiting device limits the voltage between the gate connection and the power emitter connection. A deactivation device is connected to the voltage-limiting device and deactivates the voltage-limiting device during a switch-on of the semiconductor switch.
