Renesas Expands GaN Transistor Portfolio Into Low-Voltage Power Conversion Applications

Renesas Electronics introduced its first family of 100V enhancement-mode GaN-based discrete power transistors designed for efficiency-critical applications in AI data centers, robotics, and industrial systems. The new transistors deliver ultra-fast switching speeds and superior figure-of-merit performance, achieving up to 35% lower hard-switching losses compared to competing GaN devices. The low-voltage GaN devices maintain silicon-compatible footprints, enabling easy integration into existing designs while supporting emerging 800V power distribution architectures in data center infrastructure.

Renesas' new transistor lineup targets a critical shift in data center power infrastructure. As AI servers migrate toward 800-volt direct current distribution systems paired with 48-volt bus architectures, power conversion stages require higher switching frequencies—moving from hundreds of kilohertz into the megahertz range. This transition demands components that minimize energy loss during conversion cycles while reducing the physical size of supporting magnetic and passive components.

The silicon-compatible packaging represents a practical adoption advantage. By maintaining familiar form factors, manufacturers can redesign power supply units and motor drive circuits with minimal printed circuit board modifications, accelerating time-to-market for products incorporating the new transistors across industrial automation, robotics, and renewable energy applications.
