IR HiRel, an Infineon Technologies AG company, announced fourteen newly QPL–qualified radiation-hardened (rad hard) MOSFETs housed in an innovative direct-to-PCB mounting package. SupIR-SMD is key to higher performing space power systems such as satellite bus power distribution systems, payload power supplies, space-grade DC-DC converters, and other high-switching designs.

Capable of attaching directly to the PCB, the SupIR-SMD design is optimized for surface mount attach and proven to meet the most stringent reliability testing in this configuration.

Compared to the typical packaging solution used in space applications, the SupIR-SMD delivers a 37% smaller footprint, 34% lighter mass and 33% higher current density, while offering a more direct thermal path for heat transfer.

“With this, the SupIR-SMD package is testament to IR HiRel’s commitment to deliver innovation that exceeds the specific requirements of the space market,” said Eric Toulouse, Vice-President and General Manager of IR HiRel.
