Abstract
A power semiconductor device for surface mounting includes an isolating body, a thermal dissipator and electrical connection pins. The pins and legs of the thermal dissipator extend in the direction of the lower surface of the body. During a surface mounting operation of the device on a substrate, a quantity of solder is enclosed by a capillary effect under the major part of the plate. Thus, a good electrical and thermal contact is obtained with a metallization of the substrate.
