Infineon Technologies, radiation-hardened HiRel energy units are aboard the Nancy Grace Roman Area Telescope, which lifted off from Kennedy Area Middle in Florida, marking the profitable launch of NASA’s subsequent flagship area observatory. The Roman Area Telescope will journey to the second Solar-Earth Lagrange level (L2), greater than 1.5 million kilometers from Earth, the identical orbital place because the James Webb Area Telescope, the place steady gravitational situations and an unobstructed view of a large swath of the sky will assist the mission’s scientific program. The Roman Area Telescope mission provides to Infineon’s area heritage that stretches again to the Seventies, throughout which the corporate supported a whole lot of area missions together with navigation satellites, the Worldwide Area Station, and NASA’s Artemis program, with rad-hard elements which have traveled greater than 20 billion kilometers from Earth.
“The launch marks the start of what is going to be one of the vital scientifically productive area observatory missions ever undertaken, and Infineon’s HiRel know-how is a part of that from day one,” mentioned Mike Mills, Senior Vice President and Basic Supervisor HiRel at Infineon. “Roman will function at L2 for as much as a decade with no risk of upkeep or servicing. At that distance, in that radiation atmosphere, energy know-how has to work flawlessly from day one and preserve working. Area packages require applied sciences and companions they will depend on for many years, and the collection of Infineon’s HiRel units for the Roman mission displays the qualification depth and mission heritage that the area business calls for from a strategic know-how associate.”
Past Earth’s protecting magnetic discipline, high-energy particles strike electronic components unimpeded and might completely harm or destroy them, inflicting mission failure. Infineon’s radiation-hardened know-how addresses these mechanisms not by means of passive shielding, however by means of a semiconductor structure that’s radiation-resistant by design.
Infineon’s HiRel portfolio built-in into the Roman Area Telescope consists of rad-hard energy semiconductor elements. The units are certified to MIL-PRF requirements with Whole Ionizing Dose (TID) and Single Occasion Results (SEE) characterization, offering the efficiency margins required for sustained operation at L2. Roman’s onboard techniques will downlink roughly 1.4 terabytes of uncooked science knowledge per day to floor stations in New Mexico, Australia, and Japan, representing the best knowledge quantity of any NASA astrophysics mission thus far. Dependable, steady energy supply to the telescope’s devices and knowledge techniques is a prerequisite for assembly this operational cadence throughout the total length of the mission.
Infineon’s HiRel product vary spans radiation-hardened silicon energy MOSFETs, gallium nitride (GaN) transistors, gate drivers, solid-state relays and diodes, backed by in-house fabrication, sturdy radiation testing capabilities and assured long-term product availability. Infineon’s JANS-qualified rad-hard 100 V GaN transistor, the primary and solely internally manufactured rad-hard GaN transistor in the marketplace certified per MIL-PRF-19500, represents the vanguard of this portfolio. GaN permits decrease switching losses, greater energy density, and better switching frequencies, decreasing energy losses and magnetic part necessities and delivering measurable weight and quantity financial savings on the system stage, the place each gram counts in area functions.
