    Abstract: A transistor cell region of a semiconductor device includes transistor cells that are electrically connected to a first load electrode. An idle region includes a gate wiring structure that is electrically connected to gate electrodes of the transistor cells. A transition region, which is disposed between the transistor cell region and the idle region, includes at least one sensor cell that is electrically connected to a sense electrode. The at least one sensor cell is configured to convey a unipolar current during an on state of the transistor cells.
