Onsemi, a leading intelligent power and sensing technology company, is partnering with GlobalFoundries to develop next-generation gallium nitride (GaN) power devices.

Onsemi announced on the 22nd that it will jointly develop and manufacture high-performance GaN power products based on the 200mm eMode GaN-on-Si process with GlobalFoundries, responding to the increasing power demand in high-growth markets such as AI data centers, electric vehicles (EVs), renewable energy, and aerospace.

This collaboration is considered a significant turning point in expanding ON Semiconductor's power semiconductor portfolio and securing high-voltage GaN solutions.

Through this partnership, ON Semiconductor plans to accelerate its roadmap for high-performance GaN devices, including 650V horizontal GaN solutions, and strengthen its integrated power stage product line.

In particular, it is expected to increase competitiveness in fields where high-efficiency power conversion is essential, such as AI data centers, electric vehicle charging systems, solar microinverters, and energy storage devices.

“The combination of ON Semiconductor’s system and product expertise with GlobalFoundries’ advanced GaN process will enable us to deliver new 650V power devices for high-growth markets,” said Dinesh Ramanathan, senior vice president of corporate strategy at ON Semiconductor. “ON Semiconductor will begin shipping samples to customers in the first half of 2026.”“We plan to supply the platform and quickly transition to mass production,” he said.

Mike Hogan, Chief Commercial Officer at GlobalFoundries, also said, “The combination of our 200mm GaN-on-Si platform and ON Semiconductor’s technological capabilities will accelerate the development of high-efficiency power solutions for key markets such as data centers, automotive, industrial, and aerospace,” adding, “We will strengthen the GaN semiconductor supply chain to respond to AI, electrification, and the sustainable energy transition.”

Onsemi will showcase GaN devices that combine silicon-based driver/controller technology and thermally enhanced packages with GlobalFoundries' 650V GaN platform to deliver higher power density and efficiency.

This product family is applicable to a wide range of applications, including power supplies (PSUs) for AI servers, DC-DC converters, onboard chargers (OBCs) for electric vehicles, solar microinverters, and industrial motor drives.

The key advantages of GaN technology are also noteworthy.

First, high-frequency switching can improve efficiency and thermal performance while reducing system size and component count, and bidirectional power handling capability simplifies design and reduces cost by replacing multiple conventional unidirectional transistors.

Additionally, the integrated package structure combines the driver, controller, and protection circuits into a single package, shortening the design period and reducing electromagnetic interference (EMI).

This collaboration will give Onsemi a full range of GaN technologies, from low-, medium-, and high-voltage horizontal GaN to ultra-high-voltage vertical GaN. This is expected to be a key foundation for system designers to implement next-generation power architectures that handle higher power in smaller spaces.

Onsemi plans to begin supplying samples of GaN products in the first half of 2026.
