STMicroelectronics launched its fourth generation of STPOWER silicon carbide (SiC) MOSFET technology. This new generation promises to raise the bar in terms of power efficiency, density, and robustness, particularly in electric vehicle (EV) traction inverters. The rollout will continue through 2025 with advancements in both 750V and 1200V classes, designed to bring SiC benefits to a wider range of EVs, including mid-size and compact models.
The fourth-generation SiC MOSFET technology targets the growing EV market, where the need for smaller, more efficient power systems is crucial. ST’s latest innovation will not only benefit premium electric vehicles but also make SiC technology accessible to mainstream models, improving energy efficiency and driving range. The technology is set to enhance EV traction inverters, which play a key role in electric powertrains, while also offering solutions for industrial applications like solar inverters, data centres, and energy storage systems.
Marco Cassis, President of the Analog, Power & Discrete, MEMS, and Sensors Group at STMicroelectronics, commented, “We are advancing SiC technology to help drive the future of electric mobility. Our fourth generation of SiC MOSFETs represents a significant leap forward in efficiency and performance.”
ST’s SiC technology continues to enable 800V EV bus systems that allow for faster charging and reduced vehicle weight. The introduction of the new 750V and 1200V SiC MOSFET devices will further enhance the efficiency of both 400V and 800V EV systems, crucial for mid-sized EVs.
The SiC MOSFETs are also ideal for a variety of high-power industrial applications. By improving switching performance and reducing power consumption, they are expected to lower operational costs and enhance reliability in industrial settings. This makes them suitable for renewable energy projects, server power supplies for AI datacentres, and other energy-efficient applications.
STMicroelectronics has already completed the qualification of the 750V SiC MOSFET class, with the 1200V class expected to be qualified by early 2025. Full commercial availability will follow, allowing designers to meet the demands of applications ranging from EV batteries to industrial power systems.
ST’s roadmap includes the introduction of multiple SiC innovations through 2027, with the next generation (Generation 5) already in development, promising further advancements in power density and efficiency.
As an integrated device manufacturer, STMicroelectronics is uniquely positioned to meet the growing demand for SiC technology, ensuring a resilient supply chain to support the electrification of vehicles and industrial applications.
