According to the Impress Watch website, under the trend of the decline of the Japanese semiconductor industry, some Japanese companies are still struggling in the field of power semiconductors. Japanese power semiconductor companies still have an advantage in custom products with high breakdown voltage and large capacity.

The major players in the power semiconductor market are Mitsubishi Electric, Fuji Electric, Hitachi Power Semiconductor and Toshiba Semiconductor & Storage. Among medium-sized enterprises, Roma, Sancha Electric, and Xindianyuan have performed well.

In the past year, the replacement of GaN and SiC by Ga2O3, a new generation of power semiconductor material, is rapidly gaining attention. Japan is leading the world in the field of power semiconductors based on Ga2O3.

It is reported that it is not a large company such as Mitsubishi Electric, but a government research institute, university research institute and investment institution.
