Abstract
A semiconductor device includes a semiconductor module including a high-side first transistor and a low-side second transistor, a first control board located above the semiconductor module, a drive element connected to a first gate terminal and a first source terminal of the first transistor on the first control board, and a drive element connected to a second gate terminal and a second source terminal of the second transistor on the first control board, a second control board located above the first control board, and photocouplers provided on the second control board. The semiconductor module includes a positive electrode terminal, a ground terminal, and an output terminal. The first gate terminal and the first source terminal are located at the side provided with the positive electrode terminal and the ground terminal. The second gate terminal and the second source terminal are located at the side provided with the output terminal.
