Renesas Electronics has launched a new family of 100-V enhancement-mode gallium nitride (GaN) power transistors. The four-model series is now available to improve power efficiency in high-density computing and automation environments.
Why it matters
These components address the rising power requirements of AI data centers and humanoid robotics by enabling smaller, more efficient electrical systems. The integration of silicon-compatible footprints facilitates a transition from legacy MOSFET designs to more capable GaN power architectures.
The family includes models ranging from 1.2 mΩ to 5 mΩ typical on-resistance. These devices deliver 40-70% lower switching losses compared to incumbent silicon-based solutions.
The players
Renesas Electronics
A global semiconductor supplier focused on microcontrollers, analog, and power management integrated circuits for industrial and automotive sectors.
The details
The transistors utilize FCLGA (Flip Chip Land Grid Array) packaging, which mimics the footprint of standard silicon MOSFETs to allow for direct board migration without extensive redesigns. By utilizing gallium nitride instead of traditional silicon, these FETs reduce switching losses and enable higher frequency operation. The four specific models utilize varying resistance levels to accommodate different power delivery requirements across high-performance compute and industrial hardware.
Timeline
October 14, 2026: The four new GaN FET models became commercially available.
The Tech Race
This release positions Renesas among firms accelerating the move from traditional silicon power MOSFETs to GaN-based power architectures. The shift aims to capture the market for AI data center infrastructure and industrial automation, where power density is the primary competitive bottleneck.
Engineers and product designers can integrate these FETs into new hardware layouts immediately to improve power density. The primary benefit for users is a more efficient power supply architecture in AI-heavy data centers and robotics that would previously have required larger footprints.
The takeaway
The move to GaN technology is now critical for maintaining power density in dense computing environments. Watch for industry-wide adoption metrics in AI-optimized power delivery modules throughout 2027.
