ABSTRACT:
A circuit package 2 is provided for heat dissipating power semiconductors and the like. Circuit means 10, including lead frames 12 and power conditioning components 13, is mounted on an electrically insulating thermally conductive substrate 4 and covered by an electrically insulating housing 6. Power lead frames 14 extend integrally externally of the housing 6 and have external portions 22 bent laterally across the to surface of the housing 6 to cooperate with terminal connection means 28 there below in the top wall 24 of the housing 6. Internal connection means 50 is provided for selectively connecting a peripheral power lead frame portion 46 to a central portion 52 of circuit means 10 and insulatively bypassing designated portions 54 of circuit means 10 therebetween. In one embodiment, circuit package 2 is provided in combination with an external printed circuit board 40 extending across the top surface 24 of the housing and connected to control lead frames 18 and power lead frames 14.
