Hi-Rel RF Radiation Hardened MOSFETs
International Rectifier, an Infineon Technologies company, supplies Hi-Rel RF Radiation Hardened MOSFETs for the aerospace sector. These Rad-Hard & hermetically sealed RF MOSFETs are ideally suited for space applications, satellite operations, and launch vehicles. The Hi-Rel RF Radiation Hardened MOSFETs are certified by the Defense Logistics Agency (DLA), Land and Maritime. Through IR’s Radiation Hardness Assurance (RHA) program, radiation hardness is guaranteed. The Hi-Rel RF Radiation Hardened MOSFETs can be delivered with the highest space screening level.
High LET Value of Hi-Rel RF Radiation Hardened MOSFETs The Hi-Rel RF Radiation Hardened MOSFETs have proven their radiation hardness against Single Event Effects (SEE) and are designed for reliable performance with a Linear Energy Transfer (LET) value of up to 90 MeV/(mg/cm²).
Very Low RDS(on) Value of Hi-Rel RF Radiation Hardened MOSFETs Combining a very low RDS(on) value with fast switching speeds reduces power loss and maximizes power density in today’s high-speed switching applications, such as DC/DC converters and motor controllers. Radiation Hardened MOSFETs incorporate all the established benefits of standard MOSFETs, such as voltage control and simplified adjustment for temperature stability of electrical characteristics.
High Single Event Effect (SEE) Ratings The N-channel and P-channel MOSFETs are immune to latch-up and Single Event Upset (SEU) and demonstrate an excellent Total Dose Irradiation rating of up to 500 Krad(Si). International Rectifier/Infineon’s Hi-Rel RF Radiation Hardened MOSFETs have been characterized in heavy-ion environments for SEE values. Each manufacturing batch undergoes testing for Total Ionizing Dose (TID). Pre- and post-irradiation performance is specified and verified under identical circuit and test conditions, allowing for direct comparison.
Available Package Options The hermetically sealed Hi-Rel RF Radiation Hardened MOSFETs are available in various ceramic package options. Both surface mount and through-hole products are offered. Through-hole packages include TO-39, TO-254AA, TO-257AA, TO-258AA, TO-259AA, and CerDIP-16. Modern surface mount packages such as LCC-3, LCC-18, LCC-28, SMD-0.2, SMD-0.5, SMD-1, SMD-2, SMD-3, and 14-pin Flatpack complete the product lineup. Small surface mount types like SMD-0.2 and SMD-0.5 contribute to significant weight reduction, essential for satellite applications. Hi-Rel RF Radiation Hardened MOSFETs are specified for an operating temperature range from -55°C to +150°C.
Extensive Heritage Experience Today’s aerospace and defense applications pose a major challenge for system designers. Space hardware must operate flawlessly under extreme environmental conditions, including high radiation resistance. Therefore, Hi-Rel RF Radiation Hardened MOSFETs are used in space applications. International Rectifier/Infineon has successfully met this challenge for over 20 years, offering a broad range of Hi-Rel RF and Power Radiation Hardened MOSFETs.
