Gallium nitride (GaN) semiconductor devices are gaining adoption because they deliver higher switching frequencies, lower conduction losses, and greater power density than conventional silicon devices. These advantages make GaN suitable for electric vehicle onboard chargers, DC-DC converters, data center power supplies, consumer fast chargers, 5G base stations, and defense RF systems. Manufacturers are also increasing production on larger 8-inch GaN-on-silicon wafers to improve manufacturing efficiency and reduce production costs.

Demand continues to grow as automakers increase electric vehicle production, hyperscale data centers upgrade power infrastructure, and telecom operators expand 5G networks. Fast-charging consumer electronics also support high-volume demand for GaN power integrated circuits operating between 65W and 240W. The transition from traditional silicon to wide-bandgap semiconductor materials is improving energy efficiency while reducing system size and weight across industrial and commercial applications.

Recent industry developments further support long-term growth. In September 2024, Infineon Technologies announced successful production of GaN chips on 300 mm wafers, enabling approximately 2.3 times more chips per wafer than conventional 200 mm production and reducing manufacturing costs. The company expects GaN pricing to move closer to silicon over time as production scales.

Key Market Numbers

Segment Breakdown

By Product: Power Semiconductors are expected to account for 46.0% of the global market in 2026. Demand is rising because GaN power devices offer higher switching frequencies, lower conduction losses, and greater power density than conventional silicon devices.

Analyst Quote

"The gallium nitride semiconductor device market is at an inflection point where multiple high-volume applications are scaling simultaneously. EV onboard chargers, data center power, consumer fast chargers, and 5G RF amplifiers are all pulling GaN adoption forward. The transition to 8-inch GaN-on-silicon wafer production is the key enabler because it brings device costs closer to silicon incumbents while delivering measurably superior performance." — Shambhu Nath Jha, Principal Consultant, Fact.MR.
