An electronic circuit and a method are disclosed. The electronic circuit includes: a first transistor device having a load path between a first load path node and a second load path node; and a clamping circuit connected to the load path of the first transistor device. The clamping circuit includes: a second transistor device having a load path connected in parallel with the load path of the first transistor device, and a control node; and a drive circuit configured to drive the second transistor device. The drive circuit includes a clamping element and a resistor connected in series between the first and second load path nodes of the first transistor device. The drive circuit is configured to drive the second transistor device dependent on a voltage across the resistor. The first transistor device and the clamping circuit are integrated in a same semiconductor die.
