ABSTRACT:
An element is protected without hampering an actual operation in the case where overvoltage that might damage the element is applied. A semiconductor device includes a first potential supply terminal100; a second potential supply terminal101; a protection circuit107which includes a voltage divider102electrically connected to the first potential supply terminal100and the second potential supply terminal101, a control circuit103, and a bypass circuit106; and a functional circuit108which is electrically connected to the first potential supply terminal100and the second potential supply terminal101through the protection circuit107.
