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

Claim 5:
6. A semiconductor module comprising:
a first power supply terminal connected to a first polarity side of DC power;
a second power supply terminal connected to a second polarity side of the DC power;
a plurality of semiconductor elements connected in series between the first power supply terminal and the second power supply terminal; and
a substrate including the plurality of semiconductor elements,
wherein the first power supply terminal has a first fastening portion for fastening an external terminal of the first polarity side, a first connection portion connected to the substrate, and a first intermediate portion arranged between the first fastening portion and the first connection portion;
wherein the second power supply terminal has a second fastening portion arranged adjacent to the first fastening portion for fastening an external terminal of the second polarity side, a pair of second connection portions arranged across the first connection portion and connected to the substrate, and a second intermediate portion at least a part of which faces the first intermediate portion with a predetermined gap and which is arranged between the second fastening portion and the pair of second connection portions,
wherein the substrate has a contact surface for contacting the first connection portion and the pair of second connection portions;
wherein the first intermediate portion has a first facing portion arranged to face a plane including the contact surface, a first outer extension portion arranged between the first facing portion and the first fastening portion and extending in a direction intersecting with the contact surface, and a first inner extension portion arranged between the first facing portion and the first connection portion and extending in the direction intersecting with the contact surface;
wherein the second intermediate portion has a second facing portion arranged to face the plane including the contact surface, a second outer extension portion arranged between the second facing portion and the second fastening portion and extending in the direction intersecting with the contact surface, and a pair of second inner extension portions arranged between the second facing portion and the pair of second connection portions and extending in the direction intersecting with the contact surface;
wherein the first facing portion and the second facing portion are arranged to face each other with the predetermined gap; and
wherein the first outer extension portion and the second outer extension portion are arranged to face each other with the predetermined gap.
