What happened
Renesas Electronics Corporation (TSE:6723) has expanded its GaN portfolio into low-voltage applications with its first family of 100V enhancement-mode (E-mode) GaN-based discrete power transistors.S1 The launch consists of four parts: the RTP100E005G1FL, RTP100E2P6G1FL, RTP100E1P8G1FL-DSC and RTP100E1P2G1FL-DSC.S1 The source describes the FETs as intended for AI data centers, humanoid robotics, factory automation, industrial motor drives, power tools and solar microinverters.S1
Renesas states the family delivers "up to 35 percent lower hard-switching FOM and up to 63 percent lower soft-switching FOM than comparable GaN devices."S1 The parts use a silicon-compatible footprint intended to ease migration from existing silicon MOSFET layouts, and are offered in MOSFET-compatible packages with a wide RDS(on) range from 5 milliohm to 1.2 milliohm.S1 Bottom-side and dual-side cooling variants are available.S1
The source also states that using these low-voltage GaN devices in 800V HVDC power architectures "significantly reducing passive component size, switching losses and cooling requirements," and that, depending on architecture, the devices can achieve "up to 40 to 70 percent lower switching losses and up to twice the power density at the system level."S1 Akhil Nair, Senior Director, Low-Voltage GaN at Renesas, is quoted in the source commenting on GaN adoption for AI servers, robotics, industrial motor drives and renewable energy systems.S1

XAIPART take
Technical impact
The 100V E-mode parts sit in the sweet spot for 48V bus intermediate stages and 12V/5V point-of-load conversion in AI server motherboards, where Renesas cites up to 70% lower switching losses and up to 2x power density at the system level. XAIPART analysis. The stated zero Qrr and low Qoss matter most in hard-switched topologies such as totem-pole PFC and synchronous rectification; designers moving from silicon MOSFETs should re-tune dead-time and gate-drive strength because GaN's lower Qg combined with the silicon-compatible footprint can produce faster dV/dt than legacy silicon layouts expect.
Market impact
The four part numbers with RDS(on) spread from 5 milliohm down to 1.2 milliohm let Renesas cover everything from light-load buck phases to high-current motor-drive stages in humanoid robotics and factory automation using one footprint family. XAIPART analysis. For buyers sourcing 48V conversion stages for AI rack power, this directly competes with EPC, GaN Systems, Navitas and Innoscience in the 100V E-mode GaN segment, which should pressure lead times and per-piece pricing over the next two quarters.
Action
Pull the RTP100E005G1FL, RTP100E2P6G1FL, RTP100E1P8G1FL-DSC and RTP100E1P2G1FL-DSC datasheets and characterize them against incumbent 80V/100V silicon and GaN MOSFETs in your 48V-to-POL and motor-drive reference designs. XAIPART analysis. Request EV samples from Renesas or XAIPART now, lock second-source pin-compatible GaN parts for risk, and add the family to your AI server PSU and humanoid actuator shortlists.
XAIPART Forecast
XAIPART expects that if Renesas publishes distributor stock on at least one of the four 100V E-mode GaN part numbers (RTP100E005G1FL, RTP100E2P6G1FL, RTP100E1P8G1FL-DSC or RTP100E1P2G1FL-DSC) at MOQ 100 by Q1 2027, and quoted lead time does not exceed 16 weeks, then Renesas will be a credible second source in 100V E-mode GaN alongside EPC, Navitas and Innoscience for 48V AI data center power stages.
