IR HiRel Space Systems

IR HiRel has a long history serving the space flight industry with high-reliability, radiation hardened power management solutions. We understand the engineering complexities of designing for failure-free performance in the extreme thermal, mechanical and radiation environments of space. Since 1985, customers have relied on IR HiRel solutions for mission-critical power management in thousands of space, aerospace and national security programs, ranging from space exploration vehicles to launchers and satellites. Many of these programs are still in flight today.

IR HiRel was the first to provide rad hard MOSFETs for space in 1985 and is now a leading provider of radiation hardened power management solutions. We offer a unique portfolio of standard and custom products specifically designed for the tough applications where commercial electronics fail. Our power management solutions have been part of most major defense, civil, and commercial space missions around the world.

IR HiRel’s expansive power management portfolio includes:
