Microchip's radiation-resistant MOSFETs are certified for commercial and military satellite and aerospace power solutions

     Power supplies for space applications need to operate in a radiation-resistant technology environment, protecting against extreme particle interactions and the effects of solar and electromagnetic events, which can degrade the performance of space systems and interfere with operations. To meet this requirement, Microchip Technology announced that its M6 MRH25N12U3 radiation-resistant 250V, 0.21 ohm Rds (on) metal-oxide-semiconductor field-effect transistor (MOSFET) has been certified for commercial aerospace and defense space applications.

     Microchip's radiation-resistant M6 MRH25N12U3 MOSFETs provide the primary switching elements for power conversion circuits, including point-of-load converters, DC-DC converters, motor drives and controls, and general-purpose switches. This MOSFET is designed to withstand harsh space environments, enhance the reliability of the power circuit, and meet all the requirements of MIL-PRF19500/746 with increased performance.

     The new device can withstand a total ionization dose (TID) of up to 100 krad and 300 krad and a single event effect (SEE) of linear energy transfer (LET) of up to 87 MeV/mg/cm2. In the verification test, the wafer batch radiation resistance rate of the device reached 100%.

     Leon Gross, vice president of Microchip's Discrete Products business unit, said: "Microchip's entry into the radiation-resistant MOSFETs market demonstrates our long-term commitment to supporting our customers and providing aerospace and defense Oems and integrators with high-performance solutions and continuous supply. In addition to its proven high quality and reliability, the M6 MRH25N12U3 offers developers value pricing options and comprehensive application support."

     The M6 MRH25N12U3 is part of Microchip's extensive portfolio of aerospace, defense and space technologies. These products include field programmable gate arrays (FPgas), microprocessor integrated circuits (ics), linear ics, power devices, discrete devices, and power modules that integrate SiC and Si power solutions. Together with single-chip microcomputer (MCU) and analog products, Microchip is able to meet the needs of high-power system control, gate drive, and power level, providing total system solutions to developers worldwide.
