    Abstract: A semiconductor device is disclosed with a protection device formed of a parasitic bipolar transistor, a parasitic diode and a parasitic resistance and operated at a lowered operating voltage to be capable of improving a blocking capability against an over voltage. The impurity concentration in a semiconductor layer as the base of a parasitic bipolar transistor is lower compared with the impurity concentration of a semiconductor layer of the same conduction type arranged adjacently to the semiconductor layer as the base and to be the anode of a parasitic diode. The lowered impurity concentration is determined to be the concentration for making the parasitic bipolar transistor have a snapback phenomenon occur.
