Abstract
An integrated circuit arrangement includes an IGBT, provided with a secondary contact connected with the drift area, and a diode connected between the secondary contact and the anode of the IGBT. The cathode of the diode is connected with the anode of the IGBT and the anode of the diode is connected with the secondary contact of the IGBT. In this way the pn-junction of the IGBT, formed through the drift area and the channel area, can be used as an internal free-running diode of the IGBT.
