    摘要: A transistor component includes in a semiconductor body a source zone and a drift zone of a first conduction type, and a body zone of a second conduction type complementary to the first conduction type, the body zone arranged between the drift zone and the source zone. The transistor component further includes a source electrode in contact with the source zone and the body zone, a gate electrode adjacent the body zone and dielectrically insulated from the body zone by a gate dielectric layer, and a diode structure connected between the drift zone and the source electrode. The diode structure includes a first emitter zone adjoining the drift zone in the semiconductor body, and a second emitter zone of the first conduction type adjoining the first emitter zone. The second emitter zone is connected to the source electrode and has an emitter efficiency γ of less than 0.7.
