On 15 July 2026, Infineon introduced the RIC70115, a radiation-hardened gallium nitride (GaN) HEMT driver for satellite and other high-reliability space applications. The part is rated to 100 krad(Si) total ionizing dose, characterized for single-event effects up to 81.9 MeV·cm²/mg LET, and operates across -55°C to 125°C; an evaluation board is available now. The Straits Research article also places the launch in the context of a broader radiation-hardened electronics market that is tracking growth through 2034.
Technically, this matters because GaN power stages can deliver higher efficiency and switching speed than legacy silicon, which directly improves solar power conversion, battery charging, motor drives, and thermal margins in lunar infrastructure. The 100 krad(Si) TID rating and LET characterization indicate the device is built for long-duration exposure in low-Earth orbit and beyond, making it relevant to lunar surface power systems, orbital relays, and any autonomous hardware that must function after years of cumulative radiation.
Ark action: track Infineon’s RIC70115 qualification status, package options, and system-level radiation data; benchmark it against prior Infineon rad-hard GaN parts announced on 29 May 2025 and 21 October 2025; and assess whether GaN-based gate-drive chains can be standardized for lunar power buses, habitat utilities, and propulsion-adjacent electronics. Priority research: failure modes under thermal cycling, redundancy architecture, and performance under lunar dust, vacuum, and extended dormant storage.
