ABSTRACT:
An improved semiconductor rectifier unit of the type in which two semicontor rectifier devices are electrically insulated and thermally conductively arranged in an electrical series connection so that a current conducting lead associated with the input and a current conducting lead associated with the output of the series connection as well as a third current conducting lead associated with the connecting conductor between the semiconductor devices are arranged in a row and each one of the two outer current conducting leads together with its associated semiconductor device are firmly mounted on a respective common contact plate which is fastened on the base plate via a wafer of electrically insulating thermally conductive material and in which the semiconductor devices have their contacting and connecting members accommodated in a housing including the base plate and a hollow plastic member fastened to the base plate. The base plate is trough-shaped, has a planar outer bottom surface, has a laterally extending flange on the side walls thereof, and is formed of a material which permits a permanently firm connection with components made of copper used to produce the unit as well as with components made of aluminum used to cool the unit. Means are provided on the bottom inner surface of the base plate for maintaining the wafer of insulating material in a desired position on the base plate during production of the unit. The edge portion of the plastic housing member which is adjacent the base plate is provided with a shaped region which matingly engages the flange to firmly connect the plastic housing member to the base plate.
