Abstract: A semiconductor element is provided as an electrically tested, economical, ong time storable and simple individual element for easy assembly and universal application. A semiconductor disk and an insulating body annularly surrounding the semiconductor disk are used. The insulating body is furnished with a recess substantially adapted to the edge zone of the semiconductor disk and which is also formed in the regions adjacent to the recess for a concentric disposition of contacting components on the two sides of the semiconductor disk. The semiconductor disk is supported and embedded at its edge zone in the recess of the insulating body. In case of a semiconductor disk with a gate electrode the gate current conductor is led through the insulating body and is then formed as a spring body with a rotatable and curved end piece for pressure contacting the gate electrode.

Abstract: In a semiconductor unit composed of at least two semiconductor members each rovided 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
