Abstract

A transistor device comprises: at least one individual transistor cell arranged in a transistor cell field on a semiconductor body, each individual transistor cell comprising a gate electrode; a gate contact, electrically coupled to the gate electrodes of the transistor cells and configured to switch on the at least one transistor cell by providing a gate current in a first direction and configured to switch off the at least one transistor cell by providing a gate current in a second direction, the second direction being opposite to the first direction; at least one gate-resistor structure monolithically integrated in the transistor device, the gate-resistor structure providing a first resistance for the gate current when the gate current flows in the first direction, and providing a second resistance for the gate current, which is different from the first resistance, when the gate current flows in the second direction.
