This article reviews potential domestic and overseas suppliers and key considerations when sourcing GaN semiconductor devices in Japan. Toshiba and Panasonic are cited as domestic suppliers, while overseas companies access the Japanese market through local operations.
Potential suppliers of GaN semiconductor devices include Toshiba, Panasonic, Cree, GaN Systems, Infineon Technologies, OSRAM, Efficient Power Conversion, NXP Semiconductors, Texas Instruments and NTT Advanced Technology.
Toshiba and Panasonic are cited as the 2 domestic suppliers. Toshiba develops and manufactures power semiconductors and GaN devices as a diversified electronics manufacturer and has a strong supply network in Japan. Panasonic also supplies GaN power semiconductors for its own products and industrial equipment and is regarded as an important player in Japan's electrical and electronics industry. NTT Advanced Technology is primarily engaged in communications technology and services rather than semiconductor device manufacturing, so it is not normally listed as a major supplier.
Overseas suppliers include Cree (now Wolfspeed), GaN Systems, Infineon, OSRAM, Efficient Power Conversion, NXP and Texas Instruments. They are expanding access to the Japanese market by establishing local design-support bases and partnering with local trading companies. These companies are seeking to expand business with Japanese electronics manufacturers and automotive-parts manufacturers.
