A power semiconductor module includes a housing, terminal elements leading to the outside of the housing, an electrically insulated substrate arranged inside the housing, with the substrate being comprised of an insulating body and having on the first main face facing away from the base plate a plurality of connecting tracks electrically insulated from each other. The terminal and connecting elements are arranged on a connecting track in with contact faces contacting connecting tracks or power semiconductor components, with the individual contact faces having a plurality of partial contact faces. In one optional embodiment, each partial contact face has a maximum area of 20 mm. In another embodiment, partial contact faces each are arranged at a distance of approximately 5 mm with regard to each other and the connection of the partial faces to the connecting tracks or the power semiconductor components is flush.

Power semiconductor module with flush terminal elements

A power semiconductor module with a scalable construction, having a base plate or intended for direct mounting on a heat sink. The module has a framelike housing, a cover, terminal elements, extending to the outside of the housing for load contacts and auxiliary contacts. The module having at least two electrically insulating substrates disposed inside the housing, which in turn each comprise one insulating body and a plurality of metal conducting tracks, located on the first main face of the insulating body, which first main face is remote from the base plate or the heat sink. The metal connecting tracks are electrically insulated from one another, and power semiconductor components are located on and electrically connected to these connecting tracks. The substrates () are identical, and electrically connected to one another, and have the same type and number of power semiconductor components disposed thereon.

The substrate includes an insulating body and a plurality of metal connecting tracks, electrically insulated from one another. Power semiconductor components are located on the connecting tracks and connected to these connecting tracks via appropriate circuitry. The base plate has a stiffening structure, which extends near and along a side of the base plate, and in the longitudinal direction of the base plate. The stiffening structure is formed of the base plate material itself by deformation and protrudes out of the upper surface of the base plate.
