Onsemi and GlobalFoundries (GF) are to collaborate on developing and manufacturing advanced gallium nitride (GaN) power products using GF’s state-of-the-art 200mm eMode GaN-on-silicon process, starting with 650V. This collaboration accelerates Onsemi’s roadmap for high-performance GaN devices and integrated power stages, expanding its portfolio with high-voltage products to meet the growing power demands of AI data centers, electric vehicles, renewable energy, industrial systems, and aerospace, defence and security.

“This collaboration brings together Onsemi’s system and product expertise with GlobalFoundries’s 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 centres, EVs, space applications, and beyond. We are on track to begin providing samples to customers in the first half of 2026, and scale rapidly to volume production,” said Dinesh Ramanathan, Senior Vice President of Corporate Strategy at Onsemi.

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, defence, and security applications.
