Infineon Rad-Hard Chips Power NASA Roman Telescope

Infineon’s radiation-hardened semiconductors are onboard NASA’s Nancy Grace Roman Space Telescope, which recently launched from Kennedy Space Center and will operate at the Sun-Earth L2 point, 1.5 million km from Earth. The power systems are designed to support the observatory for up to a decade in deep space.

The mission, managed by NASA’s Goddard Space Flight Center, uses Infineon rad-hard power management and point-of-load converters to regulate voltage across multiple science instruments. The Roman telescope will survey the sky in infrared, mapping dark energy, exoplanets, and large-scale cosmic structure. For electronics manufacturers, the deployment is a high-profile validation of radiation-hardened by design (RHBD) components, which must withstand total ionizing dose and single-event effects over a ten-year mission without maintenance. Infineon has not disclosed specific part numbers, but the selection signals growing demand for qualified, long-lifetime power silicon in government and commercial space programs.

For PCB and PCBA buyers, deep-space missions impose stricter requirements than standard industrial electronics: low-outgassing materials, thermal cycling from -150°C to +120°C, and signal integrity across high layer count rigid-flex or ceramic substrates. Radiation-hardened chip designs must be paired with equally robust interconnect and assembly processes to ensure decade-long reliability. As more constellations and science payloads move beyond low Earth orbit, OEMs are qualifying high-reliability multilayer PCBs, ceramic PCBs, and heavy copper boards for power distribution. The Roman telescope launch therefore serves as a bellwether for aerospace electronics supply chains, where traceability, NASA-grade inspection, and long-term component support are non-negotiable.

For buyers sourcing high-reliability boards for space-adjacent or defense programs, LT CIRCUIT offers ceramic PCBs, heavy copper PCBs, and high layer count multilayer boards with controlled impedance and thermal management tailored to long-lifetime electronics.
