CHANDLER, Arizona – Microchip Technology Inc. in Chandler, Arizona, has qualified the company’s radiation-hardened M6 MRH25N12U3 MOSFET for power electronics applications on commercial and military satellites.
Space power supplies operate in environments that require improved radiation technology to withstand extreme particle interactions and solar and electromagnetic events. These events degrade space systems and disrupt operations.
To meet this requirement, Microchip has qualified its M6 MRH25N12U3 250 volt, 0.21 Ohm Rds (on) radiation hardened MOSFET for commercial aerospace and defense space applications.
Microchip’s Radiation Cured M6 MRH25N12U3 MOSFET provides the primary switching element in power conversion circuits, including point-of-load converters, DC-DC converters, motor drives and controls, and in-use switching general.

The MOSFET withstands harsh space environments, extends the reliability of power circuits, and meets all requirements of MIL-PRF19500 / 746 with improved performance. Microchip completed testing for the Defense Logistics Agency (DLA) exam and qualification for sourcing the device into the U.S. military supply chain in June.
The device can withstand total ionizing radiation doses of up to 100 and 300 kilorads and single event effects with linear energy transfer of up to 87 MeV / mg / cm2. It provides 100% assurance of the radiation hardness of the platelet batch in validation testing.
