Patent ID: 7288853

Claim:
A solid-state device comprising: a first leg adapted to be coupled to an electrical power source, the first leg being sized to carry an electrical load of at least 0.5 amp, the first leg having a section with a first surface and an opposite, second surface, the section including through-holes; a semiconductor electrically connected to the first surface of the section of the first leg; a second leg adapted to be coupled to a load, the second leg being sized to carry an electrical load of at least 0.5 amp, the second leg having a portion overlapping the second surface of the section of the first leg, the overlapping portion of the second leg being separated from the second surface of the section of the first leg by a layer of electrically insulating material, the overlapping portion of the second leg having through-holes aligned with the through-holes of the section of the first leg; a third leg mounted on the second leg, the third leg being electrically insulated from the second leg and adapted to be connected to a control circuit; means for electrically coupling the semiconductor with the second leg and with the third leg such that the semiconductor selectively controls power transmission from the first leg to the second leg in response to control signals from the third leg; and an electrically insulating packaging material encapsulating the semiconductor, the section of the first leg and the overlapping portion of the second leg, some of the packaging material filling the aligned through-holes.
