Abstract

A MOSFET device including a power MOSFET and a current mirror MOSFET, in which the drains of the two MOSFETs are coupled in common to each other, and the gate electrodes of the two MOSFETs are linked in common to each other, and in which a diode device for protecting a gate oxide film for the current mirror MOSFET is connected between the sources of the two MOSFETs.
