Summary:A semiconductor device and a power converter using it wherein a switching power device (700) and a flywheel diode (100) are connected in series, the flywheel diode (100) includes a region (30) having a Schottky junction (16) to operate as a Schottky diode and a region (17) having a pn junction to operate as a pn diode and control operation is performed such that when current flows forwardly through the flywheel diode, the pn diode operates and when the flywheel diode recovers backwardly, the Schottky diode operates mainly.
