## onsemi Launches GaNEXUS™ Gallium Nitride Power Portfolio

onsemi has announced the release of GaNEXUS™, a new Gallium Nitride (GaN) power portfolio designed to deliver high efficiency, high power density, and improved thermal performance for applications including AI data centers, industrial automation, robotics, and energy infrastructure. The initial lineup includes GaNEXUS FETs spanning a voltage range from 40V to 650V, as well as 650V GaNEXUS Smart GaN FETs with integrated protection functions to simplify system integration and enhance reliability.

### News Highlights

- onsemi's GaNEXUS power portfolio provides high-speed switching, low switching losses, high power density, and superior thermal performance to support next-generation architectures.
- 40V to 650V GaNEXUS FETs and 650V GaNEXUS Smart GaN FETs with integrated protection are currently available for sampling (availability in Japan is yet to be determined).
- When combined with onsemi's Treo platform, which integrates sensing, control, protection, and power management, GaNEXUS enables smarter, more reliable, and robust system-level power solutions.
- By combining onsemi's silicon, EliteSiC, and GaNEXUS technologies, customers gain the flexibility to optimize efficiency, thermal performance, system size, and total cost across the entire power delivery chain.

onsemi has begun initial sample shipments in the United States. This portfolio is ideal for high-demand applications, including AI data center power supplies, 48V systems, robotics, and industrial automation.

As AI infrastructure, electrification, and industrial automation evolve, the demand for more efficient and compact power architectures is rising rapidly. For AI data centers, power consumption is projected to account for up to 9% of total US electricity generation by 2030, with power and cooling costs potentially reaching 40% of data center operational expenses.

GaNEXUS addresses these challenges by offering faster switching speeds, lower switching losses, higher power density, and superior thermal performance compared to traditional silicon-based solutions. This allows customers to downsize magnetic components and cooling systems while improving overall system efficiency, responsiveness, and reducing costs.

Antoine Jalabert, VP of the GaN Division at onsemi, stated: "Our GaNEXUS portfolio enables new architectures in power system design. We provide high flexibility to overcome the constraints of traditional power architectures while meeting customer needs for more power in limited spaces."
