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

Claim 6:
7. A semiconductor module, comprising:
a first voltage-controlled semiconductor chip, made of a SiC semiconductor material, and
a second voltage-controlled semiconductor chip, made of a Si semiconductor material, the first and second voltage-controlled semiconductor chips being connected in parallel, wherein
the first voltage-controlled semiconductor chip is a SiC-MOSFET having a body diode thereof, and
the second voltage-controlled semiconductor chip is a Si-MOSFET having a body diode thereof, the body diode of the Si-MOSFET being electrically connected in parallel to the body diode of the SiC-MOSFET, so as to turn on and off together with the body diode of the SiC-MOSFET, a forward voltage of the body diode of the Si-MOSFET being so set that, when a current flowing through the body diode of the SiC-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 Si-MOSFET at the predetermined current value.
