Reliably attaching surface mount hermetic power packages to PCBs is a common challenge faced by space system designers. Too often, different thermal coefficients lead to an expansion mismatch of different materials. IR HiRel, an Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY) company, solves this issue with 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.
