Abstract
According to one embodiment, a semiconductor device has a transistor comprising a source electrode, a drain electrode, and a gate electrode, a diode and a switch element connected in series between the gate and source electrodes of the transistor, and a control circuit configured to supply a control signal for switching the switch element. The control circuit has a predetermined time constant and is configured to supply the control signal to the switch element if a pulse signal having a voltage that is equal to or higher than a predetermined voltage is supplied to the gate electrode of the transistor.
