Aerospace Military and Defence Product of the Year
Company Name: Microchip
Product Name: JANSF2N7587U3 MOSFET
Supporting Statement:
Microchip Technology’s JANSF2N7587U3, is a 100V N-channel MOSFET qualified to JANS and rated to 300 krad(Si) Total Ionizing Dose (TID). It directly addresses some of the most critical challenges in aerospace and defence electronics, while also meeting the MIL-PRF-19500/746 slash-sheet specification.
Designed for use in the most demanding applications in terms of performance, robustness and reliability, the JANSF2N7587U3 can be employed in DC-DC converters Switch Mode Power Supplies (SMPS) and motor control designs. The device forms part of Microchip’s broader strategy to expand higher Radiation Hardness Assurance (RHA) solutions for aerospace and defence applications.
Microchip has leveraged its long history and deep expertise to develop components that are highly differentiated versus standard electronics and protect against catastrophic failures in the most demanding applications. Built on the proven JANS RH MOSFET die, the JANSF2N7587U3 is offered in multiple package options to allow engineers to closely align selection in terms of performance and cost to their application needs. This includes a cost-effective plastic package using MIL-qualified JANSR die for New Space and Low Earth Orbit (LEO) applications, as well as a hermetically sealed ceramic package designed for total dose and Single-Event Environments (SEE).
Designed to operate in the most extreme environments, from deep space missions to advanced military platforms, this product sets a benchmark for performance, reliability and cost-efficiency. With low RDS (on) and low total gate charge, power dissipation as heat is minimised increasing overall efficiency and reducing the need for thermal management; this can reduce design complexity, save cost, space and weight, and improve reliability. It represents clear benefits for all Mil / Aero applications and in especially in satellites where the advantages can translate into longer operational life and increased payload opportunities.
The product has been qualified to the MIL-PRF-19500/746 specification at the JANS level. JANS-level qualification represents the highest screening and reliability classification within the MIL-PRF-19500 system for space-grade discrete semiconductors. This underscores the device’s suitability for demanding aerospace, defence and spaceflight applications by validating that it can withstand the harshest operational conditions, such as radiation exposure, temperature extremes and long mission durations. Evidencing this, the JANSF2N7587U3 MOSFET is designed to withstand radiation exposure up to 300 krad (Si) Total Ionizing Dose (TID).
Leon Gross, corporate vice president of Microchip’s aerospace and defence group commented on the product saying: “Meeting the stringent specifications required for rad-hard MOSFETs is extremely challenging, and Microchip is pleased to achieve this development milestone by leveraging its proprietary radiation-hardened by- design process and technology. Our advanced technology provides our aerospace and defence customers with highly reliable and cost-effective solutions that meet the ever more stringent demands of the market and its applications.”
