Semiconductor device

A semiconductor device to be cooled by a refrigerant, comprising:

• a heat dissipation member;
• a plurality of switching elements each including a main electrode through which a main current flows and a plurality of pads, the main electrode in each of the switching elements being electrically connected to the heat dissipation member and the switching elements being connected in parallel with each other, the switching elements including a first switching element formed on a silicon substrate and a second switching element formed on a silicon carbide substrate;
• and
• a plurality of signal terminals electrically connected with the pads, wherein
• each of the switching elements includes, as one of the pads, a temperature sense pad for detecting a substrate temperature,
• the switching elements include at least one of the first switching element or the second switching element in a plural number,
• the first switching element and the second switching element are alternately arranged in a predetermined direction in which the refrigerant flows, and
• in the switching elements of same type as the switching element disposed on a most downstream side in the predetermined direction, the signal terminal corresponding to the temperature sense pad is provided for a part of the switching elements including the switching element disposed on the most downstream side, and is not provided for a remaining part of the switching elements disposed on more upstream side than the part of the switching elements.
