Abstract

In order to supply a load, e.g. an electric motor, with current bidirectionally, an H bridge configuration containing four switching transistors is used. In order to attain outstanding electrical conductivity and also thermal conductivity, a half-bridge configuration containing two transistors of opposite conductivity types is constructed. Each of the transistors is realized on a chip, the rear sides of which chips are seated on a common conductive support preferably produced from metal. Each housing is equipped with a support of this type. The rear side of each of the two chips is formed from a drain or source electrode of the transistors. A load can be connected to the support. Two half-bridge configurations can advantageously be combined to form an H bridge configuration.
