Abstract
The present invention implements an equivalent circuit to a semiconductor device for an upper arm by electrically connecting a terminal for ECand a terminal for K with the use of an external wiring in a semiconductor device. On the other hand, in a semiconductor device including a circuit having the same structure as the semiconductor device, an external wiring is used to electrically connect a terminal for A and a terminal for EC. Consequently, there is implemented an equivalent circuit to a semiconductor device for a lower arm which is of a different type from the semiconductor device for the upper arm.
