• The non-binding MOU outlines a strategic partnership, including wafer procurement and extended collaboration, leveraging onsemi's GaN power solutions and Innoscience's leading wafer manufacturing to target the projected $2.9 billion total addressable market1 by 2030 for GaN power devices, with the potential value in the hundreds of million dollars for both companies.
• The arrangement would assist onsemi and Innoscience in their efforts to deliver significant customer value, specifically by combining onsemi's expertise in packaging, drivers, and systems integration with Innoscience's proven wafer manufacturing capabilities.
• The two companies' technologies together are expected to enable smaller, more efficient GaN solutions for industrial, automotive, telecom infrastructure, consumer, and AI data center markets.

SCOTTSDALE, Ariz., and SUZHOU, China, Dec. 02, 2025 (GLOBE NEWSWIRE) -- onsemi and Innoscience today announced the signing of a memorandum of understanding (MoU) to evaluate opportunities to accelerate deployment of GaN power devices, starting with 40-200V, and significantly broaden customer adoption. The collaboration outlined in the MoU brings together onsemi's leadership in integrated systems and packaging with Innoscience's proven GaN technology and high-volume manufacturing to enable delivery of cost-effective, highly efficient GaN products for industrial, automotive, telecom infrastructure, consumer and AI data center markets.

GaN semiconductor devices offer higher switching speeds, smaller form factors, and lower energy losses to deliver more power in less space. Until now, limited offerings and manufacturing capacity have slowed GaN adoption in the low and medium-voltage segment. Through this collaboration, onsemi and Innoscience will seek to overcome these barriers to quickly bring high-volume, worldwide deployment of optimized GaN solutions for mainstream markets:

• Industrial: motor drives for robotics, solar microinverters, and optimizers
• Automotive: DC-DC converters, synchronous rectification
• Telecom Infrastructure: DC-DC and point-of-load converters
• Consumer and Mass Market: power supplies, adaptors, DC-DC converters, motor drives, audio, light e-mobility, power tools, robotics
• AI Data Center: intermediate bus converters, DC-DC converters, battery backup units

For onsemi customers, the collaboration with Innoscience would enable:

• Faster Time to Market: Rapid prototyping, accelerated design-in, and swift entry into mainstream markets with onsemi's system expertise and Innoscience's proven GaN technology and manufacturing
• Scalable Manufacturing: True mass-market scalability to handle large-volume ramps, leveraging onsemi's global integration and packaging experience and Innoscience's established GaN capacity
• Lower System Cost: Optimized package, fewer components and simplified thermal management deliver more compact designs and lower total system cost.
