• the circuit die having an upper side,
• a transistor, in particular a power transistor, formed in the upper side of the circuit die,
• the transistor having a conduction path which can be switched to a conducting or blocking state, said path having a first end portion and a second end portion, of which the first end portion is electrically connected with a first conduction path terminal area and the second end portion is electrically connected with a second conduction path terminal area, which are both exposed at the upper side of the carrier, and the transistor comprising a control terminal for switching the conduction path to a conducting state or blocking state,
• a light-emitting diode die comprising a light-emitting diode or a laser diode, with a lower side comprising a first terminal area and an upper side comprising a second terminal area,
• the light-emitting diode die being arranged with its first terminal area located on the first conduction path terminal area of the transistor (Tdis) and these two terminal areas being electrically connected with one another,
• a charge storage component comprising a charge storage, the charge storage component comprising a lower side having a first terminal area and an upper side having a second terminal area,
• the charge storage component being arranged with its first terminal area located on the second conduction path terminal area of the transistor and these two terminal areas being electrically connected with one another,
• at least one first bonding wire which electrically connects the second terminal area of the light-emitting diode die with the second terminal area of the charge storage component,
• a charging circuit for charging the charge storage component with electric charge, the charging circuit being integrated in the circuit die and having an output, and
• a control circuit for driving the transistor and the charging circuit, the control circuit being integrated in the circuit die,
• the charging circuit having assigned thereto a charge terminal area exposed on the upper side of the carrier, with which the output of the charging circuit is electrically connected,
• the charge terminal area of the charging circuit being electrically connected with the second terminal area of the charge storage component via at least one second bonding wire, and
