Abstract
A semiconductor device includes a main IGBT, a sense, a resistor, a MOSFET and a diode, as main components. The sense IGBT and the main IGBT are connected in parallel with each other. The drain of MOSFET is connected to the gate of the sense IGBT, the source thereof is connected to the gate of the main IGBT, and the gate thereof is connected to the emitter of the sense IGBT and the cathode of diode. One end of the resistor is connected to the gate of the main IGBT and the source of the MOSFET, and the other end of the resistor is connected to the emitter of the main IGBT and the anode of the diode.
