1. A semiconductor device comprising:

  • at least two switching circuits connected in parallel, each of the at least two switching circuits comprising at least two switching elements connected in series and a clamping diode connected to a node between adjacent switching elements of the least two switching elements;

    a base potential line, connecting auxiliary terminals of different switching circuits of the at least two switching circuits at a base potential to apply an equivalent control signal on the switching elements, that operates to deliver an equal level of potential in the parallel-connected switching circuits; and

    a wiring line connecting the respective nodes of the different switching circuits, having a current carrying capacity approximately equal to a rated current of at least one of the switching elements connected to the wiring line, and having a lower resistance value than that of the base potential line.
