Power semiconductor module with asymmetrical lead spacing

摘要

A power semiconductor has power terminals arranged in a row at one side of the housing, with control terminals arranged in a row at the other side of the housing. The spacing between adjacent power terminals is greater than the spacing between adjacent control terminals.

主权项

1. A power semiconductor module comprising:
a carrier board; a first power semiconductor component having power and control terminals, the first power semiconductor component being mounted on the carrier board; a second power semiconductor component having power and control terminals, the second power semiconductor component also being mounted on the carrier board; the power terminals of the first power semiconductor component being commonly coupled to the power terminals of the second semiconductor component; a housing having an upper surface, a lower surface and sides, the housing enclosing each of the first and second power semiconductor components and at least partly enclosing the carrier board; a plurality of electrically conductive leads connected to corresponding ones of the power and control terminals and extending to outside the housing; and wherein:
the power terminals are arranged in a row along one side of the housing;the control terminals are arranged in a row along an opposite side of the housing; and a spacing between adjacent power terminals is greater than spacings between adjacent control terminals, wherein: the control terminals of the first power semiconductor component form a first group of control terminals and are arranged alongside each other; the control terminals of the second power semiconductor component form a second group of control terminals and are arranged alongside each other; and one of the control terminals of the first group of control terminals is spaced further apart from an adjacent one of the control terminals of the second group of control terminals than the spacing between adjacent control terminals of the first group of control terminals.
