Abstract
In a bipolar power component, for example an IGBT, having an emitter structure and a drift zone of the opposite conductivity type, the emitter structure is provided with a first contact and the drift zone is provided with a second contact. The first contact and the second contact are connected to a drivable resistor circuit such that, dependent on a control signal at the resistor circuit, the current through the power component optionally flows via the first contact and/or via the second contact to a third contact of the resistor circuit.
