The JANS qualification designates the highest level of screening and acceptance conditions, ensuring the superior performance, quality and reliability of discrete semiconductors for aerospace, defence and spaceflight applications. Microchip Technology has completed its family of rad-hard power MOSFETs to the MIL-PRF-19500/746 slash-sheet specification and the attainment of JANSF qualification for its JANSF2N8587U3, 100V N-channel MOSFET to 300Krad (Si) Total Ionizing Dose (TID).
The company's JANS series of rad-hard power devices is provided in voltage ranges from 100–250V to 100Krad (Si) TID. The family is expanding to higher Radiation Hardness Assurance (RHA) levels, starting with the JANSF2N7587U3 at 300Krad (Si) TID. The JANS RH MOSFET die is provided in multiple package options, including a plastic package using the MIL-qualified JANSR die, delivering a cost-effective power device for New Space and LEO applications. The ceramic package is hermetically sealed and developed for total dose and SEE.
The devices are designed to meet the MIL-PRF19500/746 standard with enhanced performance, making them excellent options for applications that demand high-reliability components capable of withstanding the harsh environments of space and extending the reliability of power circuitry.
"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 rad-hard by design process and technology," said Leon Gross, corporate vice president of Microchip's discrete products group. "Our advanced technology provides our aerospace and defence customers with highly reliable and cost-effective solutions that meet the growing demand of the market and their applications."
The JANSF and JANSR RH power MOSFETs serve as the primary switching elements in power conversion circuits, including PoL converters, DC-DC converters, motor drives and controls, and general-purpose switching. With low RDS(ON) and a low total gate charge, these power MOSFETs offer improved energy efficiency, lowered heat generation and improved switching performance when compared to similar devices on the market.
The company offers a wide portfolio of high-reliability solutions designed for aerospace and defence, including RT and RH MCUs, FPGAs and Ethernet PHYs, power devices, RF products, timing solutions, and discrete components from the bare die to system modules. It also offers a wide range of components on the QPL to better serve its customers.
There are Spice Models available for the JANS MOSFETs, supplying further resources for software simulation and design optimisation.
