The Semiconductor & Device Group provides semiconductors and devices that play a key role for home to space appliances and enrich our living. We recognize energy and environmental issues as today's social issues and contribute to a low-carbon society by providing low-power products to customers.

In order to achieve sustainable societies, it is imperative to use generated power while minimizing power loss in the process. Power semiconductor devices are incorporated into a number of power electronics, playing a significant role in reducing power loss. In addition, Mitsubishi Electric manufactures state-of-the-art products using silicon carbide (SiC) as a means of helping to create low-carbon societies.

The Semiconductor & Device Group provides high-performance, high-efficiency, compact high-frequency devices and optical devices for wireless communications equipment and optical fiber communications that make full use of multiple semiconductor technologies. Furthermore, by reducing the space required for communications equipment, the cooling function can be simplified, thereby contributing to comprehensive energy savings.

Industrial-use TFT color LCD modules provide a mercury-free, low-power consumption option owing to the white LED backlight used in them. We have an extensive lineup of LCD modules that are used in measuring equipment, construction and agricultural machinery, machine tools, and POS terminals.

SiC-SBD (discrete)

From the viewpoint of energy savings and environmental protection, Mitsubishi Electric is developing semiconductor devices using silicon carbide (SiC), the material physical attributes of which can significantly contribute to reducing power loss, and expanding the product lineup.
In fiscal 2011, we were the first company in the world to equip air conditioners with SiC power semiconductor modules. Since then, we have promoted their use in various products such as rolling stock and industrial equipment. We launched the SiC-SBD*1 (discrete), which reduces power loss by approximately 21%*2 compared to our conventional products. By expanding the lineup, it contributes to improving the efficiency, reducing the size, and lighter electric vehicle power supply systems used for charging batteries, photovoltaic power systems, air conditioners, and more.
We will continue to accelerate the development of new technologies and products to respond to diverse needs for energy efficiency.

25 Gbps EML CAN

Data transmission volume has been rapidly increasing with the widespread use of handheld mobile communication devices and the storage of information on cloud networks. In response to these trends, the construction of large-volume, high-speed optical communications systems is being planned between base stations where traffic is concentrated and exchanges where communication signals from base stations are centrally controlled. In November 2018, Mitsubishi Electric launched a new optical communications device that is used to connect the base stations in such networks. The 25 Gbps*1 EML*2 CAN*3 has improved the speed and volume of mobile communications systems and reduced energy consumption, thus contributing to energy efficiency.

  1. *1 Gbps (Gigabits per second): Unit of communication rate. 1Gbps indicates that 1 billion digital codes can be transmitted per second.
  2. *2 EML (Electro-absorption Modulated Laser diode)
  3. *3 CAN (TO-CAN): Package with excellent productivity (mass production capacity) widely used in optical communications devices.

Transflective Series TFT-LCD Modules that Reduce Power Consumption

Transflective Series TFT-LCD modules* use outside light as a light source in bright outdoor environments (in reflective mode) and as backlight in dark places (in transmissive mode). Because of their high visibility, even in direct sunlight, and lower power consumption owing to the use of outside light, demand is mounting for use in portable industrial measuring equipment. Expansion of the product lineup will help reduce power consumption of displays installed in a wide range of industrial devices used outdoors.

  1. * Transflective Series TFT-LCD modules: TFT-LCD modules that form two different areas (transmissive and reflective parts) within a single pixel and have a structure to reflect outside light on a substrate.
