Abstract
Provided is a switching element including: a first switching element primarily used for formation of a two-way current path; and a second switching element that interrupts a parasitic diode at the time when the first switching element is turned off. The second switching element may be of smaller chip size because it assists the operation of the first switching element, thereby contributing miniaturization of the switching element and reduction in an ON resistance. Furthermore, adoption of the switching element to a protection circuit realizes reduction in the size of the protection circuit.
