Company Overview
Mitsubishi Electric's Semiconductor & Device business supplies power semiconductors, high-frequency devices and optical devices. Power modules are used in electric vehicles, railways, industrial drives, renewable-energy systems, air conditioners and other equipment that must convert electricity efficiently.
The semiconductor operation benefits from Mitsubishi Electric's knowledge of factory automation, traction, energy and electrical systems. Its main domestic power-device network is centered in Fukuoka, Kumamoto and Fukuyama.
Mitsubishi Electric is differentiated by the connection between semiconductor devices and the industrial systems that use them. It can develop modules with an understanding of inverters, traction, factory equipment and thermal requirements, not only transistor specifications.
Technology & Products
IGBT modules
Power modules for industrial, automotive, rail and consumer applications.
SiC power devices
High-efficiency devices and modules for higher-voltage conversion.
Power modules
Integrated switching modules with packaging and thermal technologies.
High-frequency devices
RF devices for communications and other high-frequency systems.
Optical devices
Laser and optical semiconductor products for communications and sensing.
Power-device application support
Evaluation and design resources for system integration.
Position in the Supply Chain
The group converts semiconductor wafers into power chips and modules, then supplies system makers that build inverters, traction equipment, industrial machinery and energy infrastructure.
Strategic Position
Mitsubishi Electric is expanding power-device production while strengthening module assembly and inspection. Vertical knowledge from end systems can guide reliability, packaging and application-specific development.
Ecosystem Impact
Its Kyushu operations contribute to Japan's power-semiconductor cluster and link fabs with module assembly, equipment, materials and automotive and industrial customers.
