Microchip Technology has announced a significant milestone with the completion of its radiation-hardened (rad-hard) power MOSFET family, designed to meet the rigorous demands of extreme environments. These MOSFETs are now available with Total Ionizing Dose (TID) ratings ranging from 100 Krad to an impressive 300 Krad 1. This development ensures reliable performance in high-radiation conditions such as space, defense systems, and other critical applications.
The JANS qualification, representing the highest level of screening and acceptance criteria, guarantees unparalleled quality and reliability for discrete semiconductors used in aerospace, defense, and spaceflight missions. Notably, Microchip’s JANSF2N8587U3, a 100V N-channel MOSFET, has achieved JANSF qualification at 300 Krad (Si) TID, marking a significant advancement in rad-hard technology 3.
Key Features of Microchip’s Rad-Hard MOSFETs
Microchip’s JANS series of rad-hard power devices is engineered to operate across voltage ranges from 100V to 250V, with TID capabilities extending up to 300 Krad (Si). These devices are ideal for applications requiring robust performance under extreme conditions, including space exploration and defense systems 4.
- Multiple Package Options: The JANS RH MOSFET die is available in both plastic and ceramic packages. Plastic packages utilize MIL-qualified JANSR dies, offering cost-effective solutions for New Space and Low Earth Orbit (LEO) applications. Ceramic packages, on the other hand, are hermetically sealed and specifically developed for total dose and Single-Event-Environments 3.
- Enhanced Performance: These MOSFETs are designed to comply with the MIL-PRF19500/746 standard, ensuring exceptional performance in harsh environments. They extend the reliability of power circuitry, making them indispensable for satellite systems, electric vehicles, and renewable energy applications 6.
Applications Across Industries
The JANSF and JANSR rad-hard power MOSFETs serve as primary switching elements in various power conversion circuits. Their key applications include:
- Point-of-Load Converters: Delivering efficient power management in compact designs.
- DC-DC Converters: Ensuring stable voltage regulation in demanding environments.
- Motor Drives and Controls: Providing precise control and enhanced energy efficiency.
- General-Purpose Switching: Supporting versatile use cases across industries.
With low RDS(ON) and minimal total gate charge, these MOSFETs offer improved energy efficiency, reduced heat generation, and superior switching performance compared to competing devices 4.
Why Microchip’s Rad-Hard MOSFETs Stand Out
Developing radiation-hardened components that meet stringent industry standards is no small feat. Microchip’s proprietary “rad-hard by design” process and cutting-edge technology have enabled the company to achieve this milestone, providing aerospace and defense customers with highly reliable and cost-effective solutions 3.
“Meeting the stringent specifications required for rad-hard MOSFETs is extremely challenging,” said Leon Gross, Corporate Vice President of Microchip’s Discrete Products Group. “Our advanced technology addresses the growing demand for high-reliability components, empowering our customers to tackle the challenges of modern applications with confidence.” 3
