• Infineon provides long‑term product availability and in‑house radiation testing

Pulse Analysis

Artemis II’s successful lunar flyby not only marked a milestone for human spaceflight but also served as a high‑stakes validation platform for aerospace‑grade electronics. As the Orion capsule ventured beyond Earth’s protective magnetosphere, Infineon’s radiation‑hardened (rad‑hard) components endured intense high‑energy particle exposure, proving that the company’s IR HiRel portfolio can sustain mission‑critical functions from power conversion to data handling. This real‑world test complements extensive ground‑based qualification, offering operators confidence that the hardware will survive the harsh space environment without degradation.

Infineon’s rad‑hard lineup blends mature silicon MOSFETs with cutting‑edge gallium nitride (GaN) technology, delivering a unique mix of low switching losses, high power density, and reduced magnetic component requirements. The 100‑V rad‑hard GaN transistor, the sole device of its class meeting MIL‑PRF‑19500, exemplifies this advantage, enabling lighter, more efficient power architectures for spacecraft where size, weight, and power budgets are at a premium. All products meet stringent standards—MIL‑PRF‑38535 Class V, ESA ESCC, and NASA EEE‑INST‑002—ensuring cross‑agency compatibility and simplifying certification pathways for future missions.

The broader market impact is significant. With commercial and governmental entities accelerating deep‑space exploration, demand for reliable, long‑life rad‑hard components is rising sharply. Infineon’s commitment to in‑house radiation testing and guaranteed product availability positions it as a preferred supplier for next‑generation lunar, Martian and beyond missions. As spacecraft become more electrified and data‑intensive, the company’s proven performance on Artemis II will likely drive increased adoption of its GaN and silicon solutions across the rapidly expanding space‑technology ecosystem.
