Abstract:
A semiconductor device comprising:a semiconductor component; and a connection board, the semiconductor component having: an essentially cylindrical housing, which housing, for electrical connection of the semiconductor component, comprises an anode on one end, a cathode on another end and, in a plane between the anode and the cathode, an annular gate connection, which projects laterally from the housing and concentrically surrounds the housing, which semiconductor component, for low-inductance connection to a drive circuit accommodated on the connection board, is arranged in a mounting opening in the connection board, in such a way that the gate connection is located parallel to the connection board on one side of the connection board and projects beyond an edge of the mounting opening and is connected there to said one side of the connection board, and that the cathode is located on another side of the connection board and is connected to said another side of the connection board via a connection; and an auxiliary cathode connection of the semiconductor component to the connection board, the auxiliary cathode connection having a concentric annulus which projects laterally and parallel to the gate connection beyond the housing and projects beyond the edge of the mounting opening.
