Rad-hard MOSFETS qualified for commercial aerospace/defense space apps
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. 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. […]
GaN transistors, ICs feature radiation hardening
EPC announces the introduction of a new family of radiation-hardened gallium nitride transistors and integrated circuits. With higher breakdown strength, faster-switching speed, higher thermal conductivity, and lower on-resistance, power devices based on GaN significantly outperform silicon-based devices. The lower resistance and gate charge enable faster power supply switching frequencies resulting in higher power densities, higher […]
