A modular construction power circuit arrangement is disclosed which comprises a thin metal plate performing holder and heat sink functions, a multiplicity of electronic devices in the form of semiconductor material chips having metalized pads as their terminals, a printed circuit board attached to the thin metal plate, electric conductors between the metalized pads and the printed circuit on the board, terminating connectors which form a part of the printed circuit board for connecting the circuit arrangement to external circuits, and a plastics material body which conglomerates a portion of the thin metal plate, the semiconductor material chips, and the printed circuit board. At least one of the semiconductor material chips is attached directly to the thin metal plate and extends therefrom through an opening in the printed circuit board.
