The invention relates to a power semiconductor device with a substrate with a cooling device and power semiconductor components connected thereon, having load current terminal elements and a cooling device. Pressure devices have a pressure element is arranged movably in a direction normal (N) to the substrate, and an elastic deformation element between the pressure element and a load current terminal element. The pressure element presses the assigned load current terminal element against an electrically conductive contact area of the substrate via the elastic deformation element and provides electrically conductive pressure contacting of the assigned load current terminal element with the substrate. The electrical connection of the power semiconductor device is improved.

Power semiconductor device comprising a substrate and load current terminal elements

A power semiconductor module, and method for its manufacture, comprising a first housing part having a cutout and a DC voltage load connection apparatus forming a structural unit, wherein the DC voltage load connection apparatus has first and second DC voltage load connection elements. The first DC voltage load connection element has a first leadthrough section arranged in the cutout, and the second DC voltage load connection element has a second leadthrough section arranged in the cutout forming a gap therebetween. The first and second leadthrough sections are sheathed by an elastomer, which fills the gap, is cohesively connected to the first and second leadthrough sections and seals off the first and second leadthrough sections with respect to the first housing part. The inventive power semiconductor module exhibits a high resistance to thermal cycling, and the distance between the DC voltage load connection elements can be configured to be small.
