Radiation-Hardened MOSFET Qualified for Commercial and Military Satellites and Space Power Solutions
June 08 2021 - 8:05AM
Power supplies in space applications operate in environments that
require enhanced radiation technology to withstand extreme particle
interactions and solar and electromagnetic events. These events
degrade space-based systems and disrupt operations. To meet this
requirement, Microchip Technology Inc.
(Nasdaq:
MCHP) today announced the qualification of its
M6 MRH25N12U3 radiation-hardened
250V, 0.21 Ohm Rds(on), metal–oxide–semiconductor field-effect
transistor (MOSFET) for commercial aerospace and defense space
applications.
Microchip’s radiation-hardened 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 general-purpose switching. The MOSFET withstands
the harsh environments of space, extends reliability of power
circuitry and meets all requirements of MIL-PRF19500/746 with
enhanced performance. Microchip completed testing for Defense
Logistics Agency (DLA) review and qualification, for the device’s
sourcing in the U.S. military supply chain (expected JANSR2N7593U3
certification in June 2021).
The M6 MRH25N12U3 MOSFET is designed for future
satellite system designs as well as serving as an alternate source
in existing systems.
The device can withstand total ionizing dose (TID)
up to 100 krad and 300 krad and single event effects (SEE) with
linear energy transfer (LET) up to 87 MeV/mg/cm2. It provides
100-percent wafer lot radiation hardness assurance in validation
tests.
“Microchip’s entry into the radiation-hardened
MOSFET market reflects our long-term commitment to support our
customer base and provide aerospace and defense OEMs and
integrators with high-performance solutions and continuous supply,”
said Leon Gross, vice president of Microchip’s Discrete Product
Group business unit. “In addition to our proven quality and
reliability, the M6 MRH25N12U3 provides a value pricing option for
developers and offers them full application support.”
The M6 MRH25N12U3 is part of Microchip’s broad
portfolio of aerospace, defense and space technology that includes
field programmable gate arrays (FPGAs),
microprocessor integrated circuits (ICs), linear ICs, power
devices, discretes and power modules that integrate both SiC and Si
power solutions. Together with its microcontrollers (MCUs) and
analog products, Microchip serves the needs of high-power system
control, gate drive and power stage – supporting developers
worldwide with total system solutions.
While continuing to introduce new technology,
Microchip teams with space manufacturers and integrators to secure
supply chains for existing and future systems.
