The present invention relates to an electronic device for switching currents and a method for producing such a device that is reliable and durable. Such an electronic device comprises a power semiconductor that can be actuated for switching between at least two states; a substrate having thermomechanical properties compatible with the power semiconductor on which the power semiconductor is disposed on one side; a bus bar disposed on the other side of the substrate for conducting the current, wherein the substrate and the bus bar are coupled to each other such that a heat-conductive connection is provided so that heat can be dissipated from the power semiconductor to the bus bar.
