In a semiconductor unit composed of at least two semiconductor members each provided at each end with a respective current contact, a housing including a metallic base plate and a cover, elements for mounting the semiconductor members in electrically insulated and thermally conductive communication with the base plate, external connecting leads, and spring elements for establishing pressure contact between the leads and the current contacts, the connecting leads include a lower lead in the form of a contact rail contacting the current contact at that end of each member which is directed toward the base plate and interposed between the base plate and the members, and an upper lead for each member arranged concentrically with its respective member and contacting the current contact at that end of its associated member which is directed toward the cover, the contact rail includes a free end region which extends through an opening in the housing to provide an external connection in a selected connection plane, the cover is provided with an opening for each upper lead through which the upper leads extend to provide further external connections, and the unit further includes a structure securing each upper lead against rotation relative to the housing. |
