Abstract
A semiconductor device that can suppress variation of GND potential of a control board and prevent malfunction of IC without restricting a mounting direction of the IC of the control board is provided. In a power moduleas a semiconductor device in which an insulating boardhaving a power switching elementand a control boardhaving ICfor controlling the power switching elementare vertically provided in a case body, GND pinsare provided at both the sides of the IC, a GND patternto which the GND pinsof the ICare connected is provided in the control board, and a GND loop breaking slitas a breaking portion for breaking a GND loop formed by electrical connection of the IC, the GND pinsat both the sides of the ICand the GND patternis provided to the GND pattern
