GaN Power Device Market Size & Share Analysis - Growth Trends and Forecast (2026 - 2031)

Global GaN Power Device Market Trends and Insights

AI Data-Center Power Demand And High-Voltage DC Architectures

The move toward 800 V high-voltage DC architectures is increasing the relevance of the GaN power device market in AI training and inference infrastructure. Onsemi stated in June 2026 that power and cooling can account for as much as 40% of hyperscale data-center operating expenses, so small efficiency improvements can have material operating effects at large loads. GaN supports high-density conversion in 800 V-to-48 V and 48 V intermediate-bus stages, where switching speed and lower losses can reduce equipment and cooling demands. Navitas has worked with NVIDIA on 800 V HVDC power architectures for IT racks of 1 MW and above, placing GaN and SiC technologies within the applicable power-conversion architecture.^[1]This work shifts the discussion from a component replacement toward system design, where design support and qualified supply carry more weight. The GaN power device market can benefit as hyperscalers qualify these architectures and suppliers convert design activity into production orders.

Electrification And Higher Power Density In EV Charging

Electric vehicle on-board chargers require compact designs that can handle rising power ratings, which supports the GaN power device market. Navitas reported in April 2025 that its high-power GaNSafe ICs achieved AEC-Q 100 and AEC-Q 101 qualification after more than 7 years of production data, more than 250 million units shipped, and field failure rates approaching 100 parts per billion across more than 2 trillion device-hours. Changan Automobile brought a GaN-based on-board charger using GaNSafe technology into commercial production, with production ramping during 2026. The shift from 6.6 kW chargers toward 11 kW and 22 kW systems can increase the number of power switches used in each vehicle. This raises GaN content per vehicle in addition to growth in electric vehicle volume. The GaN power device market, therefore, depends on both vehicle platform adoption and the power rating selected for each charger.

Fast-Charging And Compact Consumer Power Supplies

Consumer electronics remained an important volume base for the GaN power device market, holding 44.3% of revenue in 2025. The European Commission stated that around 2 billion external power supplies were in service in the European Union and consumed an estimated 11.6 TWh each year.^[2] Commission Regulation (EU) 2025/2052 updates ecodesign requirements for external power supplies, wireless chargers, and USB Type-C cables. EUR-LEX These rules favor designs that can meet tighter active-efficiency requirements while retaining a compact form factor. Navitas reported that its 650 V IsoFast ICs can support single-stage bidirectional designs with up to 50% less size and 20% energy savings than two-stage silicon topologies. Consumer products also provide manufacturing volume, reliability data, and supply-chain learning that later support automotive and industrial qualifications.

Energy-Efficiency Regulation And Lower System Losses

Efficiency regulation is making power conversion performance more relevant to procurement decisions in the GaN power device market. The EU Ecodesign framework and Regulation (EU) 2025/2052 set minimum active-efficiency requirements for external power supplies. EUR-LEX The U.S. Department of Energy maintains efficiency requirements for certain external power supplies, while Japan and South Korea also use energy-efficiency programs that influence product design. Lower switching losses can also reduce cooling infrastructure needs in industrial and data-center installations. This can offset some of the higher component costs when operators evaluate the full system rather than a single device. The effect can take time because regulations must flow through OEM design cycles and supplier qualification processes. The combined regulatory direction gives suppliers a reason to improve qualified designs before compliance dates affect purchasing at scale.

Higher Manufacturing And Qualification Cost Versus Silicon

Higher manufacturing and qualification costs limit adoption in price-sensitive areas of the GaN power device market. GaN wafer costs were stated to be 3x-5x above comparable silicon devices because GaN-on-silicon epitaxy adds process steps and defect-management requirements. Automotive parts also require AEC-Q101 stress testing, power-cycle testing, and extended accelerated lifetime testing. These activities can add 12 - 18 months to a design cycle, even where the underlying process is mature. Suppliers with qualified products gain an entry advantage, but the same qualification burden can slow new product introductions. Expansion of 8-inch GaN-on-silicon production in Asian fabs is expected to lower device costs before 2028, although that does not remove the need for system-level validation.

Gallium, Wafer, And Epitaxy Supply Concentration

Gallium supply concentration remains a structural risk for the GaN power device market. The U.S. Geological Survey reported that China supplied 99% of the world's primary low-purity gallium production in 2025, while U.S. gallium import prices averaged USD 580 per kilogram in 2025, compared with USD 277 per kilogram in 2021. China’s restrictions on gallium exports and extraction-related technologies have raised concern over supply availability and the cost of developing alternatives. The U.S. Department of Defense awarded USD 29.9 million in November 2025 for a Louisiana gallium-recovery demonstration facility, and the Department of Energy committed up to USD 6 million for domestic extraction research. Non-Chinese output was only 14,000 kg in 2025 compared with the estimated Chinese production of 900,000 kg. This gap can make long-term pricing and supply commitments harder for device manufacturers and their customers.
