Abstract
A semiconductor component including a housing for a semiconductor substrate, an anode, a cathode, an annular gate electrode flange, which laterally protrudes from the housing and concentrically surrounds the housing, and an annular auxiliary cathode flange, which protrudes from the housing and makes contact with the cathode.
Claims14
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.

A semiconductor component for arrangement in a mounting opening of a connection board having an accommodated drive circuit, said component comprising:
- 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, when arranged in said mounting opening, is arranged, for low-inductance connection to a drive circuit accommodated on 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 for 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.
