SCOTTSDALE, AZ and SUZHOU, China, Dec 3, 2025 – onsemi and Innoscience signed a memorandum of understanding (MoU) to evaluate opportunities to accelerate the deployment of GaN power devices, starting with 40-200V, and expand their use across customer applications. The MoU combines onsemi’s integrated systems and packaging with Innoscience’s GaN technology and manufacturing to develop cost-effective GaN devices for industrial, automotive, telecom, consumer, and AI data center markets.
GaN semiconductor devices provide higher switching speeds, smaller sizes, and lower energy losses, enabling power delivery in less space. Limited product options and manufacturing capacity have slowed GaN adoption in low- and medium-voltage markets. Through this collaboration, onsemi and Innoscience will work to address these constraints and support deployment of 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 markets with onsemi’s system expertise and Innoscience’s GaN technology and manufacturing
- Scalable Manufacturing: True mass-market scalability to handle large-volume ramps, using onsemi’s integration and packaging experience and Innoscience’s GaN capacity
- Lower System Cost: Optimized package, fewer components and simplified thermal management deliver compact designs and lower system cost
“As power demands rise across every sector, GaN offers higher efficiency, smaller size, and lower energy losses compared to other materials. Until now, in the low and medium voltage segments, cost and supply constraints have limited its widespread adoption. Through a collaboration with Innoscience, we expect to be able to access the industry’s largest GaN production footprint and quickly scale our GaN offerings for customers worldwide to enable broader adoption in mainstream power applications.” said Antoine Jalabert, vice president of corporate strategy, onsemi.
“GaN technology is essential to improving electronics, creating smaller, more efficient power systems, saving electric power, and reducing CO2 emissions. Innoscience is excited to explore a strategic collaboration opportunity with onsemi, to expand and accelerate the adoption of GaN power worldwide, and to create a system integration platform with onsemi’s broad portfolio.” added Yi Sun, senior vice president, product & engineering, Innoscience.
A Complete Intelligent Power Portfolio
GaN is expected to reach about $2.9 billion, or 11% of the global power semiconductor market by 2030, with a projected compound annual growth rate from 2024-2030 of 42%1. The partnership with Innoscience would extend onsemi’s power device portfolio across silicon, silicon carbide (SiC), and GaN to support power systems used in AI data centers, automotive, industrial and consumer. The low- and medium-voltage portfolio strengthens onsemi’s position in integrated power systems as electrification and AI-energy demand increases.
