Mitsubishi Electric Begins Sample Shipments of Industrial NX-Type 1.2kV IGBT Modules

Industrial NX-Type 1.2kV IGBT Module (CM1000DX-24M)

Mitsubishi Electric Corporation will sequentially begin sample shipments of 10 models of its new power semiconductor module, the "Industrial NX-Type 1.2kV IGBT (*2) Module," starting June 15. These modules are used in inverters and large-capacity motor drive systems (*1) that control machine tools and industrial robots. By mounting the latest 8th-generation IGBT, power loss is reduced by a maximum of approximately 19% (*3) compared to conventional products, contributing to lower power consumption in inverters for industrial equipment.

This product is scheduled to be exhibited at the "PCIM Expo & Conference 2026" (June 9-11, Nuremberg, Federal Republic of Germany) and at exhibitions held in Japan, China, and elsewhere.

In recent years, the demand for power semiconductors, which efficiently convert electric power, has been expanding as key devices that contribute to the realization of a decarbonized society. Among them, industrial power semiconductor modules are used in inverters that efficiently operate and control motors used in factory machine tools and industrial robots. Toward a decarbonized society, the importance of further reducing power consumption in industrial equipment is increasing, and higher-efficiency, higher-output products are required for the power semiconductor modules used in them.

Since equipping its power semiconductor modules with IGBTs in 1990, the company's products have been highly evaluated for their excellent performance and high reliability, and are used in a variety of applications including consumer, automotive, industrial, power, and railway sectors. In particular, for the IGBT, which greatly contributes to product performance, the company has continued development aiming for lower power loss and higher reliability. As the latest generation, the 8th-generation IGBT featuring proprietary SDA (*4) and CPL (*5) structures was developed.

The "Industrial NX-Type 1.2kV IGBT Module," for which sample shipments will now begin, is equipped with the latest 8th-generation IGBT and contributes to lower power consumption in inverters. Additionally, by optimizing the chip layout of the IGBT and diode, a new 1000A rated current product—1.25 times (*6) that of conventional products—has been added to the lineup in the same package, contributing to higher inverter output. Furthermore, by continuing to adopt the industrial NX-type package, replacement from conventional products is easy, contributing to shorter inverter development times.

In response to the expected expansion in power semiconductor demand, the company will continue to rapidly and stably supply products that meet market needs, accelerating the energy conservation of power electronics equipment in various fields and contributing to GX (Green Transformation).

■ Features of the New Product

1. Equipped with the latest 8th-generation IGBT, reducing power loss by a maximum of approx. 19% compared to conventional products, contributing to lower power consumption of inverters

- By adopting the proprietary SDA (*4) structure, dv/dt (*7), which causes noise generation (a challenge in high-speed switching operations), is suppressed. Compared to the 7th-generation IGBT, it enables an increase in switching speed and reduces power loss during turn-on.

- By adopting the proprietary CPL (*5) structure, overvoltage during turn-off, which can lead to IGBT destruction, is suppressed, and the IGBT chip is made thinner. This reduces power loss during turn-on, turn-off, and conduction.

- With these features, power loss is reduced by up to approx. 19% (*3) compared to products equipped with conventional 7th-generation IGBTs, contributing to lower power consumption in inverters.

2. New lineup of a maximum rated current 1000A product, 1.25 times that of conventional products, contributing to higher inverter output

- By optimizing the chip layout of the IGBT and diode, a new 1000A rated current product—1.25 times (*6) that of conventional products—has been added to the lineup in the same package. This contributes to higher inverter output.

3. Package compatibility with conventional products contributes to shorter inverter development times

- By continuing to adopt the industrial NX-type package and keeping the external dimensions and terminal positions the same, it makes replacement from currently adopted conventional products easy, contributing to shorter inverter development times.
