Abstract:
1. A semiconductor device comprising: a power semiconductor array formed of a plurality of power semiconductors aligned and spaced in one direction, said power semiconductors each including an emitter electrode and a collector electrode; and a diode array spaced apart from said power semiconductor array in a direction intersecting with said one direction and formed of a plurality of diodes aligned and spaced in said one direction, said power semiconductor array including a first power semiconductor located on one end of said power semiconductor array, a second power semiconductor located on another end, and a third power semiconductor located between said first power semiconductor and said second power semiconductor, said diode array including a first diode located on one end of said diode array, a second diode located on another end, and a third diode located between said first diode and said second diode, a resistance value between said emitter electrode and said collector electrode in ON state being higher at said third power semiconductor than at said first power semiconductor and at said second power semiconductor, and upon application of a voltage of not less than a rising voltage, said third diode having a higher resistance value than resistance values of said first diode and said second diode upon application of a voltage of not less than a rising voltage.
