Microchip’s radiation-tolerant M6 MRH25N12U3 MOSFETs provide the primary switching elements for power conversion circuits, including point-of-load converters, DC-DC converters, motor drive and control, and general-purpose switches. This MOSFET device can withstand harsh space environment, enhance the reliability of power supply circuit, and meet all requirements of MIL-PRF19500/746 with higher performance.

The M6 ​​MRH25N12U3 MOSFET can be used in future satellite systems or as a backup power supply for existing systems.

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

“Microchip’s entry into the radiation-tolerant MOSFET market reflects our commitment to supporting our customers with high-performance solutions and continued supply for aerospace and defense OEMs and integrators,” said Leon Gross, vice president of Microchip’s discrete products business unit. Long-term commitment. In addition to 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 line of aerospace, defense and aerospace technology products. 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. Coupled with microcontroller (MCU) and analog products, Microchip can meet the needs of high-power system control, gate drive and power stage, and can provide global developers with total system solutions.

As Microchip continues to introduce new technologies, it also seeks to work with aerospace product manufacturers and integrators to secure the supply chain of existing and future systems.
