TORRANCE, Calif., Oct. 13, 2025 (GLOBE NEWSWIRE) — Navitas Semiconductor (Nasdaq: NVTS), the industry leader in next-generation GaNFast™ gallium nitride (GaN) and GeneSiC™ silicon carbide (SiC) power semiconductors, announced progress in its development of advanced medium and high 800 VDC voltage GaN and SiC power devices to enable the 800 VDC power architecture announced by NVIDIA for next-generation AI factory computing platforms.
With the emergence of the ‘AI factory’, a new class of data center purpose-built for large-scale, synchronous AI and high-performance computing (HPC) workloads, has introduced a set of power challenges. Traditional enterprise and cloud data centers, which rely on legacy 54 V in-rack power distribution, are unable to longer meet the multi-megawatt rack densities required by today’s accelerated computing platforms. These challenges call for a fundamental architectural shift.
800 VDC power distribution provides:
- Higher efficiency by reducing resistive losses and copper usage
- Scalable infrastructure to deliver MW-scale rack power with highly compact solutions
- Global alignment with the IEC’s low-voltage DC (LVDC) classification (≤1,500 VDC)
- Simplified power distribution with efficient thermal management
The 800 VDC architecture enables direct conversion from 13.8 kVAC utility power to 800 VDC within the data center power room or perimeter. By leveraging solid-state transformers (SSTs) and industrial-grade rectifiers, this approach eliminates multiple traditional AC/DC and DC/DC conversion stages, maximizing energy efficiency, reducing losses, and improving overall system reliability.
The 800 VDC distribution directly powers IT racks, eliminating the need for additional AC-DC conversion stages, and is stepped down through two high-efficiency DC-DC stages (800 VDC to 54 V/12 VDC, and then to point-of-load GPU voltages), to drive advanced infrastructure such as the NVIDIA Rubin Ultra platform.
These state-of-the-art AI factories demand unprecedented levels of power density, efficiency, and scalability, which can be enabled by Navitas’ high-performance GaNFast and GeneSiC technologies.

As a pure-play wide bandgap power semiconductor company, Navitas delivers breakthrough GaN and SiC technologies that enable high-efficiency and high-power density power conversion across every stage of the AI data center, from the utility grid to the GPU.
Navitas’ new 100 V GaN FET portfolio delivers superior efficiency, power density, and thermal performance in advanced dual-sided cooled packages. These FETs are specifically optimized for the lower-voltage DC-DC stages on GPU power boards, where ultra-high density and thermal management are critical to meet the demands of next-generation AI compute platforms. Samples, datasheets, and evaluation boards are available for qualified customers.
Additionally, these high efficiency 100V GaN FETs are fabricated on a 200 mm GaN-on-Si process through a new strategic partnership with Power Chip, enabling scalable, high-volume manufacturing.
Navitas’ 650 V GaN portfolio includes a new line of high-power GaN FETs, alongside advanced GaNSafe™ power ICs, which integrate control, drive, sensing, and built-in protection features. This ensures exceptional robustness and reliability, supporting the demanding performance and safety requirements of next-generation AI infrastructure.
GaNSafe™ is the world’s safest GaN platform, featuring ultra-fast short-circuit protection (maximum 350 ns response), 2 kV ESD protection on all pins, elimination of negative gate drive, and programmable slew-rate control. All these features are controlled with 4-pins, allowing the package to be treated like a discrete GaN FET, requiring no VCC pin.
Enabled by over 20 years of SiC innovation leadership, GeneSiC™ proprietary ‘trench-assisted planar’ provides exceptional performance over temperature, delivering high-speed, cool-running operation for high-power, high-reliability applications. GeneSiC technology offers the industry’s broadest voltage range, stretching from 650 V to 6,500 V and has been implemented in multiple megawatt-scale energy storage and grid-tied inverter projects, including collaborations with the U.S. Department of Energy (DoE).
“As NVIDIA drives transformation in AI infrastructure, we’re proud to support this shift with advanced GaN and SiC power solutions that enable the efficiency, scalability, and reliability required by next-generation data centers,” said Chris Allexandre, President and CEO of Navitas. “As the industry moves rapidly toward megawatt-scale AI computing platforms, the need for more efficient, scalable, and reliable power delivery becomes absolutely critical. The transition from legacy 54 V architectures to 800 VDC is not just evolutionary, it’s transformational.”
“Navitas is undergoing a fundamental transformation, driven by the convergence of GaN and SiC technologies to power the world’s most advanced systems. From grid to GPU, our focus now extends far beyond mobile, as we address the megawatt-scale demands of AI factories, smart energy infrastructure, and industrial platforms with differentiated, high-performance power solutions.”
