Abstract
A power semiconductor module includes a plastic housing having an interior. A substrate in the form of a ceramic plate with upper and lower surfaces is inserted in the housing as a housing bottom. Metallizations are disposed on the upper and lower surfaces of the ceramic plate. The metallization on the upper surface of the ceramic plate faces the interior of the housing and is structured to form conductor paths. Power semiconductor components, connecting elements and terminal elements for external termimals all are disposed on the upper surface of the ceramic plate. A frame is connected to the substrate in the interior of the housing for sealing against moisture.
