Abstract
A semiconductor device has a semiconductor element connected to an input/output terminal and a reference voltage terminal, a first rectifier element connected between the input/output terminal and the reference voltage terminal, which performs rectifier operation to prevent a voltage of the input/output terminal from becoming higher than a voltage of the reference voltage terminal by a predetermined value or more, and a second rectifier element connected between the input/output terminal and the reference voltage terminal, which performs rectifier operation to prevent the voltage of the reference voltage terminal from becoming higher than the voltage of the input/output terminal by a predetermined value or more.
