Raising the Bar for Space Reliability: Microchip’s JANS Power MOSFETs and Next-Gen Solutions
Our new JANS power MOSFETs are setting new standards for reliability and performance in the demanding environment of space. Qualified to the highest radiation assurance levels, these components ensure efficient power management for satellites and other space applications. With a broad portfolio of radiation-hardened solutions, Microchip is enabling the next generation of reliable and efficient space systems.
Imagine preparing for a journey to the most unforgiving environment known to humankind—outer space. Just as a mountaineer relies on specialized gear to survive the harshest peaks, satellites and spacecraft depend on highly reliable, robust components to operate in the extreme conditions of space.
In this post, you’ll discover how our new JANS power MOSFETs and other high-reliability components are powering the future of space missions. We’ll explore recent reliability milestones, highlight key products and share resources to help you understand the evolution of satellite power systems.
Operating in space requires components that can withstand radiation, extreme temperatures and the vacuum of space. As satellite and space mission demands grow, the need for high-performance, radiation-hardened solutions has never been greater. Microchip has established itself as a leader in providing such solutions, offering a wide range of products for processing, control, communications, RF, timing and power delivery.
Reliability and Qualification Milestones
We have completed the qualification of our power MOSFET family to the MIL-PRF-19500/746 standard, achieving the highest levels of screening and radiation assurance. The JANS series, including the JANSF2N7587U3, is now qualified to withstand up to 300 Krad (Si) Total Ionizing Dose, meeting the rigorous demands of aerospace, defense and spaceflight applications.
Expanding the Power Portfolio for Space
Our radiation-hardened, hermetic power MOSFETs now cover voltage ranges from 100–250V, with screening to 100 Krad (Si) TID and new family members supporting even higher RHA. These devices will be available in multiple package options, including cost-effective plastic packages for New Space and LEO applications, and hermetically sealed ceramic packages for total dose and single-event environments.
Performance and Efficiency Advantages
JANSF and JANSR MOSFETs serve as primary switching elements in power conversion, motor control and general-purpose switching. Their low RDS(ON) and total gate charge deliver improved energy efficiency, reduced heat generation and enhanced switching performance compared to alternative devices.
