The power electronics industry is undergoing a significant transformation, driven by the growing adoption of gallium nitride (GaN) power solutions. Infineon Technologies has published the 2026 edition of its annual GaN Insights, providing valuable awareness into the world of GaN technology, its applications, and future prospects.
“GaN has become a market reality that has gained traction across various industries,” said Johannes Schoiswohl, Head of GaN Systems Business Line at Infineon. “At Infineon, we are committed to delivering value to our customers quickly and efficiently. Our product-to-system approach, combined with our leading manufacturing expertise and a broad GaN portfolio, enables us to provide our customers with the solutions they need to succeed in the market. We strive to maintain Infineon’s position as a trusted partner that can help our customers navigate the complexities of GaN technology and unlock its full potential.”
According to analysts, the GaN power semiconductor market is expected to reach almost $3 billion by 2030, marking a 400% increase compared to the 2025 market. This rapid growth is driven by significant production ramps, which began in 2025, broadening GaN adoption across multiple industries and enabling its penetration into new applications. In fact, the market is expected to grow at a compound annual growth rate (CAGR) of 44% from 2025 to 2030, with revenue projections of $920 million in 2026, representing a 58% growth over 2025.
Advancements in GaN product innovation
In 2026, designers are expected to uncover new uses of GaN bidirectional switches (BDS) beyond solar inverters and EV on-board chargers. Infineon’s high-voltage bidirectional GaN switches feature a revolutionary common drain design with a double gate structure, leveraging proven Gate Injection Transistor (GIT) technology. This unique architecture enables the use of the same drift region to block voltages in both directions, resulting in a significantly reduced die size compared to conventional back-to-back arrangements. For instance, utilising Infineon’s CoolGaN BDS, which operates up to 1MHz, solar microinverters deliver 40% more power in the same-sized inverter while reducing system costs.
GaN technology is expanding into new applications
GaN is expanding into various industries, including AI data centres, robotics, electric vehicles, renewable energy, and emerging fields such as digital health and quantum computing. In the data centre market, GaN-based power supplies with new topologies are achieving higher than ever efficiencies and power densities, reducing power losses by up to 30% and enabling the deployment of more efficient and compact data centre architectures. GaN-based motor drives used in humanoid robots can be 40% smaller in size and increase fine movement control.
Why Infineon and Infineon GaN?
Infineon is known for its innovative solutions in silicon (Si), silicon carbide (SiC), and GaN. The company’s Integrated Device Manufacturing (IDM) strategy and system understanding provide cutting-edge technologies that cater to the evolving needs of industries. Empowered by 300mm GaN wafer manufacturing, Infineon’s GaN products demonstrate exceptional performance leading to application advantages. For instance:
