Over 25 years, IR has continuously exceeded engineers expectations at delivering RAD-Hard MOSFETs that meet the extreme environmental conditions of space including exposure to severe ionizing radiation which necessitates the use of radiation-hardened components.

HiRel Rad-Hard MOSFETs

 

IR offers standard Rad-Hard DC-DC and EPC design platforms for most satellite design applications. While the converter assemblies feature mostly surface mount components on a PCB with and without an enclosure, International Rectifier also has unique design, fabrication and assembly expertise in space qualified thick film hybrid technology allowing the integration of a hybrid design minimizing material costs and miniaturization of an assembly’s form factor.

Space Applications

International Rectifier’s radiation-hardened devices are recognized for their excellent reliability with unparalleled design heritage and are at the heart of systems powering mankind’s most mission critical applications. You will find us throughout the world and above it, in missiles, launch vehicles, LEO/MEO and GEO satellites and space exploration vehicles.
