Global Semiconductor Leaders in Multiple Electronic Applications Typical Semiconductors (StMicroelectronics, ST; New York Stock Exchange Code: STM) Launches third-generation STPOWER silicon carbide (SiC) MOSFET transistor [1], advancement in electric vehicle power system power The frontier application of the device, and in other scenarios applications with high power density, high energy efficiency, high reliability.

As a leader in the SIC power MOSFET market, the integrated semiconductor integrates advanced design technology, further excavation of SiC's energy saving potential, and continues to promote the change of electric vehicles and industrial markets. With the accelerated development of electric vehicles, many vehicle manufacturers and supporting suppliers are using 800V drive systems to speed up the charging speed to help reduce the weight of electric vehicles. The new 800V system can help the vehicle manufacturers produce a long mileage longer. The new generation of SiC devices for the semiconductor design optimization for these high-end automotive applications, including electric vehicle power motor inverters, car chargers, DC / DC converters, and electronic air conditioning compressors. A new generation of products is also suitable for industrial applications, improve energy efficiency of drive motors, renewable energy converters, and energy storage systems, telecommunications power, data center power supplies.

EDOARDOMERLI, vice president of the product department of STMicotors and Discrete Devices, said: "We continue to advance this exciting technology development, constantly innovate in both chips and packages. As a full-controlled supply chain SiC product manufacturer, we can provide customers with performance-continuous improvement products. We are constantly investing in the automotive and industrial projects, and 2024 we will expect the semiconductor SiC revenue to reach $ 1 billion. "

STMicroelectronics currently completed the third-generation SIC technology platform-related standard certification, most products derived from the technical platform are expected to meet commercial maturity before 2021. The nominal voltage of 650V, 750V to 1200V will be listed, and the designers are developed from the city to electricity, and the electric vehicle high-voltage batteries and charger power supply provide more options. The first batch of listed products are SCT160N75G3D8AG with 650V SCT040H65G3AG and 750V die.

Reference technical information

The latest plane MOSFETs for semiconductors use a new third-generation SiC technology platform to establish new quality factors (FOM) benchmarks, and industry-recognized FOM (TO) X die area and ron x grid The extreme charge (QG)] algorithm represents the energy efficiency, power density and switching performance of transistors. Improveing ​​FOM with ordinary silicon technology becomes more difficult, so SIC technology is the key to further improve the FOM. The third generation SiC product of the semiconductor will lead the transistor FOM progress.

The unit area of ​​the silicon carbide MOSFET is high than the radical rating than the silica-based MOSFET, and is the best choice for electric vehicles and fast charging infrastructure. There is also an advantage that the parasitic diode switching speed is very fast, and the current bidirectional flow characteristics are suitable for electric vehicles to supply the infrastructure from the vehicle battery to the vehicle battery. In addition, the switching frequency of the SiC transistor is very high, providing a possible passive device in the power supply system, so that more compact and lightweight electrical equipment can be used in the vehicle. These product advantages also help to reduce the cost of ownership in industrial applications.

The third generation of semiconductors has a variety of packages, including die, discrete power packages (STPAK, H2PAK-7L, HIP247-4L, and HU3PAK) and ACEPACK series power modules. These packages provide innovative features to designers, for example, specially designed cooling sheets simplify the connection of the board and the electric vehicle application of the electric vehicle, so that the designer can select a special-purpose chip according to the application, for example, power motor inverter , In-vehicle charger (OBC), DC / DC converter, electronic air conditioning compressor, industrial applications, such as solar inverters, energy storage systems, motor drives and power supplies.
