Electrification and power-efficiency requirements accelerate adoption of gallium nitride and silicon carbide devices across high-voltage applications

Posté 2026-10-08 04:53:39

The global Gallium Nitride and Silicon Carbide Discrete Devices Market was valued at USD 2.49 Billion in 2025 and is projected to reach USD 9.81 Billion by 2035. Demand is increasing as electric vehicles, renewable power systems, industrial equipment, and data centers require power semiconductors that can operate at higher temperatures, voltages, and switching frequencies. The International Energy Agency reported that global electric car sales exceeded 17 million in 2024 and are expected to surpass 20 million in 2025, increasing demand for efficient power electronics in vehicles and charging infrastructure. The U.S. Department of Energy also identifies wide-bandgap semiconductors such as SiC and GaN as important technologies for improving power conversion efficiency and reducing energy losses.

KEY GROWTH DRIVERS

Wide-bandgap semiconductors allow power systems to operate at higher switching frequencies and temperatures while supporting smaller and more efficient power-conversion designs. Silicon carbide is gaining adoption in electric vehicle traction inverters, onboard chargers, renewable-energy inverters, industrial drives, and grid equipment, while gallium nitride is expanding in high-frequency charging, consumer electronics, telecommunications, and data-center power supplies. Growth in electric mobility is creating additional demand because higher power density can reduce the size and weight of power-conversion systems. Renewable generation and battery-storage projects are also increasing the need for efficient inverters and power-management components. For instance, in February 2025, Infineon Technologies, Germany, announced its CoolSiC MOSFET 650 V family with a focus on high-efficiency power conversion for applications including solar energy, energy storage, electric vehicle charging, and industrial power supplies. These are some of the key factors driving revenue growth of the Gallium Nitride and Silicon Carbide Discrete Devices Market.

MARKET RESTRAINTS

However, wide-bandgap discrete devices face high manufacturing and material costs compared with established silicon alternatives. SiC wafer production and substrate quality remain important cost considerations, while GaN manufacturing requires specialized device structures, packaging, and reliability testing. Supply-chain concentration across semiconductor materials and fabrication capacity can also create procurement risks for device manufacturers. These factors are expected to limit Gallium Nitride and Silicon Carbide Discrete Devices Market growth to some extent over the forecast period.

SEGMENT HIGHLIGHTS

The Silicon Carbide segment accounted for the leading position in the market in 2025. SiC discrete devices are widely suited to high-voltage and high-power applications because they offer lower switching losses and high-temperature operating capability. Their adoption in electric vehicle traction systems, fast chargers, photovoltaic inverters, industrial power supplies, and energy-storage systems supports broad demand.

The Gallium Nitride segment is expected to register faster growth during the forecast period. GaN devices can operate at high switching frequencies and support compact power-conversion designs. This makes them suitable for fast chargers, consumer electronics, telecom equipment, data centers, and other applications where size, efficiency, and power density are important. Increasing demand for compact charging systems and high-efficiency power supplies is expanding the addressable market for GaN discrete devices.

REGIONAL OUTLOOK

North America remains an important market because of investment in electric mobility, renewable power, semiconductor manufacturing, and data-center infrastructure. The U.S. Department of Energy has identified wide-bandgap semiconductor technologies as an area for improving power electronics efficiency and has supported research and development programs focused on SiC and GaN devices. U.S. investment in domestic semiconductor manufacturing is also supporting development of the broader power semiconductor supply chain.

Europe is supported by the region's automotive electrification targets and industrial energy-efficiency requirements. The European Commission reported that battery-electric vehicles represented a growing share of new vehicle registrations in the European Union in 2025, reinforcing demand for efficient traction and charging systems. European semiconductor manufacturers, including Infineon Technologies, are expanding SiC and GaN portfolios for automotive, renewable-energy, and industrial applications.

Asia Pacific is expected to register the fastest growth during the forecast period. The region combines large semiconductor manufacturing capacity with high electric vehicle production, expanding renewable-energy installations, and strong electronics manufacturing activity. China's Ministry of Industry and Information Technology has continued to support development of the semiconductor sector and advanced power-electronics technologies through industrial policy and manufacturing programs. Japan and South Korea are also major semiconductor and automotive production centers, creating demand for SiC and GaN components across vehicle, consumer electronics, industrial, and energy applications.
