Semiconductor device
The semiconductor device improves heat dissipation by loading a diode and a MOSFET or IGBT in a single package. A drain electrode disposed on a rear surface of a MOSFET chip is soldered to an upper surface of a first lead frame, and a cathode electrode disposed on a rear surface of a diode chip is soldered to an upper surface of a second lead frame. Rear surfaces of the first lead frame and second lead frame to which neither the diode chip nor the MOSFET chip is connected are disposed so as to be exposed from a sealing resin.
