Renesas Electronics has introduced a family of four 100-V enhancement-mode discrete gallium nitride (GaN) power transistors. These new components are designed to boost power efficiency in high-density applications.
Why it matters
The company developed these transistors to address the growing power demands of AI data centers, humanoid robotics, and industrial factory automation. They offer significant improvements in switching losses and overall power density compared to traditional alternatives.
The new 100-V GaN FETs achieve up to 70% lower switching losses and support twice the system-level power density of existing solutions. Available models feature on-resistances ranging from 1.2 mΩ to 5 mΩ in FCLGA packages.
The players
Renesas Electronics
A prominent global supplier of semiconductor products, including microcontrollers, analog, power, and SoC solutions.
The details
Engineered with a silicon-compatible footprint, the FCLGA packages allow engineers to migrate from silicon MOSFET layouts without significant PCB rework. The four-model lineup includes the RTP100E005G1FL, RTP100E2P6G1FL, RTP100E1P8G1FL-DSC, and RTP100E1P2G1FL-DSC.
Timeline
The new low-voltage GaN power transistors became available on October 14, 2026.
The Tech Race
The industry is increasingly shifting from traditional silicon MOSFET layouts to gallium nitride materials to handle higher thermal loads. This development positions Renesas to compete more effectively in the high-performance computing and robotics power markets.
Developers and systems engineers can now improve hardware efficiency and reduce physical component footprints in power systems. These transistors enable more compact designs for AI infrastructure and advanced robotics without requiring complete circuit board redesigns.
The takeaway
Advancements in GaN technology provide essential power density improvements for the next generation of industrial and computing hardware. Manufacturers should evaluate their current power stages to determine if transitioning to these low-resistance FCLGA packages could enhance system performance.
