Infineon’s 2026 edition of GaN Insights eBook highlights adoption in power electronics
Infineon Technologies AG of Munich, Germany has published the 2026 edition of its annual GaN Insights, focusing on GaN gallium nitride (GaN) technology, its applications and future prospects, as the increasing adoption of GaN power solutions is driving a significant transformation in the power electronics industry.
“GaN has become a market reality that has gained traction across various industries,” notes Johannes Schoiswohl, head of the GaN Systems business line. “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,” he adds. “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.”
Yole Group’s ‘Power GaN 2025’ report forecasts that the GaN power semiconductor market will grow by 400% from 2025 to almost $3bn by 2030. 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, TrendForce’s ‘2025 Global GaN Power Device Market Analysis’ forecasts a compound annual growth rate (CAGR) of 44% from 2025 to 2030, with revenue projections of $920m in 2026. This represents 58% growth over 2025, according to Yole’s ‘Power GaN 2025’ report.
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 what is claimed to be 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, utilizing 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 expanding into new applications
GaN is expanding into various industries, including AI data centers, robotics, electric vehicles, renewable energy, and emerging fields such as digital health and quantum computing. In the data-center 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-center architectures. GaN-based motor drives used in humanoid robots can be 40% smaller in size and increase fine movement control.
Infineon’s GaN
Infineon’s portfolio of power semiconductors spans silicon (Si), silicon carbide (SiC), and GaN solutions. The firm says that its integrated device manufacturing (IDM) strategy and system expertise provide technologies accommodating the evolving needs of industries. Empowered by 300mm GaN wafer manufacturing, its GaN products are claimed to demonstrate exceptional performance leading to application advantages. For instance:
- The new CoolGaN Transistor 650V G5 generation of products have figures-of-merit (the product of conduction loss and switching loss) 30–40% better than others in the industry, substantially increasing system performance and design degrees of freedom.
- CoolGaN Transistor MV G5 products have monolithically integrated a Schottky diode, resulting in 15% lower losses and >10% lower device temperature, translating to reduced size and cost with higher efficiency and reliability.
- Bolstering its position as the world’s leader in automotive semiconductors, Infineon’s new CoolGaN Automotive 100V product meets the rigorous requirements of the AEC-Q101 standard to address the application shift from 12V to 48V systems in the newest generations of automobile architectural designs.
With a broad portfolio of over 50 GaN products, offering both discrete and highly integrated solutions, spanning voltages from 40V to 700V targeted for consumer, industrial and automotive applications, Infineon says that it provides an extensive set of solutions spanning a wide range of power applications.
Available on Infineon’s website, the GaN Insights eBook explores the existing state of GaN technology, products, their applications, and the opportunities and challenges that lie ahead.
