Assignee: FUJI ELECTRIC CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A semiconductor module, comprising:
a metal-oxide-semiconductor field effect transistor (MOSFET) made of a SiC semiconductor material, the MOSFET having a body diode; and
an insulated gate bipolar transistor (IGBT) that is made of a Si semiconductor material and is connected in parallel with the MOSFET, wherein
the IGBT is a reverse conductive-IGBT (RC-IGBT), and includes a free wheeling diode, and
the free wheeling diode is electrically connected in parallel to the body diode of the MOSFET, so as to turn on and off together with the body diode of the MOSFET, a forward voltage of the free wheeling diode being so set that, when a current flowing through the body diode of the MOSFET is greater than or equal to a predetermined current value, the forward voltage is equal to or below a source-drain voltage of the MOSFET at the predetermined current value.
