    摘要: 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.

    摘要: An emitter of a thyristor is divided into a plurality of emitter regions. An electrode is provided next to each of these regions, and a turn-off current path proceeds via this electrode from the base adjoining the emitter region over a first field effect transistor to a main terminal of the thyristor. Every emitter region is also connected to this main terminal via a second field effect transistor which is integrated into the semiconductor body of the thyristor, or is manufactured in thin-film technology.
