American chip companies onsemi and GlobalFoundries (GF) have agreed to develop and manufacture gallium nitride (GaN) power products. Specifically, they will GF’s state-of-the-art 200mm eMode GaN-on-silicon process, starting with 650V.

The collaboration accelerates onsemi’s roadmap for high-performance GaN devices and will expand its portfolio with high voltage products to meet growing power demands for AI data centers, electric vehicles, renewable energy, industrial systems, as well as aerospace, defense, and security.

Fusion of Technologies

onsemi will pair its industry-leading silicon drivers, controllers, and thermally enhanced packages with GF’s 650V GaN technology platform to deliver optimized GaN devices with higher power density and efficiency. These include power supplies and DC-DC converters for AI data centers, onboard chargers and DC-DC converters for electric vehicles, solar microinverters and energy storage systems, motor drives and DC-DC converters, for industrial and aerospace, defense, and security applications.

Dinesh Ramanathan, Senior Vice President of Corporate Strategy, onsemi, said, “This collaboration brings together onsemi’s system and product expertise with GlobalFoundries’ advanced GaN process to deliver new 650V power devices for high-growth markets. Paired with our silicon drivers and controllers, these GaN products will enable customers to innovate and build smaller, more efficient power systems for AI data centers, EVs, space applications, and beyond.”

Meanwhile, Mike Hogan, Chief Business Officer, GlobalFoundries, said, “By combining our 200mm GaN-on-Si platform and U.S.-based manufacturing with onsemi’s deep system and product expertise, we’re accelerating high-efficiency solutions and building resilient supply chains for data centers, automotive, industrial, aerospace and defense, and other critical markets.”

This effort expands onsemi’s leading power semiconductor portfolio, which now includes the full spectrum of GaN technologies – from low, medium and high voltage lateral GaN to ultra high-voltage vertical GaN – enabling system designers to build next-generation power architectures that deliver more power in smaller footprints.

onsemi will begin sample shipment of the product by first half of 2026.
