Abstract
A semiconductor device includes a transistor; a diode configured to be connected in reverse-parallel with the transistor; a sense transistor configured to have a current flow in the sense transistor, depending on a current flowing in the transistor; a sense diode configured to have a current flow in the sense diode, depending on a current flowing in the diode; a resistor configured to have one terminal connected with an emitter of the sense transistor and an anode of the sense diode, and another terminal connected with an emitter of the transistor and an anode of the diode; and a current mirror configured to be connected in parallel with the resistor, and to output a current depending on a current flowing in a same direction as a forward direction of the sense diode.
