Claim 0:
1. A sealed interface for a power module, comprising:
a printed circuit board comprising a contact pad for power conduction to a bus bar of the printed circuit board;
a semiconductor module comprising at least one power transistor;
a terminal pin electrically coupled to the power module; and
a housing for the power module, the housing comprising an open terminal aperture that extends through the housing, wherein:
the printed circuit board is seated upon the open terminal aperture, to close and seal the open terminal aperture, with the contact pad positioned within the open terminal aperture;
the terminal pin contacts the contact pad of the printed circuit board within the open terminal aperture; and
the open terminal aperture comprises a transitional feature to abate electric field intensity around an interface between the open terminal aperture and the printed circuit board.
