Semiconductor device having a switching element that suppresses a potential fluctuation

摘要

The semiconductor device (11, 111, 211) is provided with a plurality of switching elements (14) connected in parallel with each other and a plurality of return elements (15) connected in parallel with the aforementioned plurality of switching elements. An emitter electrode (14b) serves as a reference potential of the aforementioned plurality of switching elements, and an anode electrode (15b) serves as a reference potential of the aforementioned plurality of return elements electrically through the same plate-like member (17) made of a conductive material are connected. The above-mentioned switching elements and the above-mentioned return elements connected in parallel on the lowest potential side are configured such that the distance from the emitter terminal (11n) connected to the above-mentioned emitter electrode to the above-mentioned return element does not become larger is considered to be the distance from the above-mentioned emitter terminal.
