Infineon's radiation-hardened HiRel power semiconductors support the NASA Nancy Grace Roman Space Telescope, operating at the L2 point with high reliability and radiation resistance to ensure continuous power for data downlinking. The technology includes rad-hard silicon and gallium nitride components, crucial for long-term operation in a harsh space environment.

This Wire brief sits within Fusion42's coverage of Semiconductors.

◆ ◆ The Wire takeaway

You must factor radiation-hardened semiconductors like Infineon's into design if you build tech for space observatories. Their use at L2 shows customers now expect components that guarantee flawless decade-long operation in high-radiation environments.
