The 100V, 35A MOSFETs are suited to mission-critical applications requiring an operating life up to and beyond 15 years. Target applications include space-grade DC/DC converters, intermediate bus converters, motor controllers and other high speed switching designs.
Developed by the Infineon IR HiRel business, the IRHNJ9A7130 and IRHNJ9A3130 are fully characterised for TID (Total Ionising Dose) immunity to radiation of 100 and 300kRads respectively. An R DS(on) of 25mΩ (typical) is 33% lower than the previous device generation. In combination with increased drain current capability (35 versus 22A), this allows the MOSFETs to provide increased power density and reduced power losses in switching applications.
The MOSFETs have improved Single Event Effect (SEE) immunity and have been characterised for useful performance with Linear Energy Transfer (LET) up to 90MeV/(mg/cm²); at least ten percent higher than previous generations. Both of the new devices are packaged in a hermetically sealed, lightweight, surface mount ceramic package (SMD-0.5) measuring 10.28×7.64×3.12mm. They are also available in bare die form.
