Abstract:
A diode includes a first-conductivity-type barrier region disposed between a drift region and a second impurity region and having an impurity concentration higher than that of the drift region and a second-conductivity-type field extension prevention region disposed between the barrier region and the drift region. The diode also includes a trench gate disposed to extend from a second main surface of a semiconductor substrate through the second impurity region and the barrier region and reach the field extension prevention region. The trench gate has a gate electrode for applying a gate voltage. A gate electrode is applied with a parasitic gate voltage, as the gate voltage. The parasitic gate voltage has an absolute value of a potential difference with a second electrode being equal to or greater than a threshold voltage of a parasitic transistor formed of the second impurity region, the barrier region, and the field extension prevention region.

Claim (Index 6):
The semiconductor device according to  claim 3 , further comprising:\n a diode current detection unit configured to detect a current value of a diode current flowing between the second electrode and the first electrode during the reverse conductive mode, wherein the drive unit applies the parasitic gate voltage as the gate voltage on condition that the diode current detected by the diode current detection unit is a predetermined threshold or less.
