Abstract
A very high power semiconductor device package has a heavy flat conductive terminal which carries a semiconductor die. A thin conductive tab is disposed to be continuous with but insulated from the terminal and lies in a plane above the heavy flat terminal. A top electrode of the die is connected to the tab and an insulation housing encloses portions of the adjacent ends of the tab and terminal as well as the die and its connector leads. The free end of the tab may have printed circuit connection fingers. Two notches are cut into the sides of the thin tab at a location closely spaced from the surface of the housing through which the tab extends to provide stress relief for the insulation housing through which the tab extends.
