Abstract
This semiconductor device comprises: an n-type semiconductor substrate which is connected to an output terminal; a first p-type well which is formed in the n-type semiconductor substrate; a first n-type semiconductor region which is formed in the first p-type well and is connected to a control terminal; and a potential separation part which is connected between the first p-type well and a ground terminal. The potential separation part sets the first p-type well and the ground terminal to a same potential when the output terminal is held at a higher potential than the ground terminal, and sets the first p-type well and the output terminal to a same potential when the output terminal is held at a lower potential than the ground terminal.
