Vitesco Technologies and onsemi sign SiC long-term supply agreement

Vitesco Technologies is providing an investment of $250 million to onsemi for new equipment for SiC boule growth, wafer production and epitaxy to secure access to SiC capacity. The equipment will be used to produce SiC wafers to support Vitesco Technologies’ growing SiC demand. In parallel, onsemi will continue to invest substantially into end-to-end SiC supply chain.

In addition, Vitesco Technologies and onsemi will collaborate on optimised customer solutions for Vitesco Technologies. onsemi’s highly efficient EliteSiC MOSFETs will be used by Vitesco Technologies to execute the recent orders as well as future projects for traction inverters and electric vehicle drives. “Energy-efficient silicon carbide power semiconductors are at the beginning of a big surge in demand.

That is why it is imperative for us to get access to the complete SiC value chain together with onsemi. With this investment we have a secure supply of a key technology over the next ten years and beyond,” said Andreas Wolf, CEO of Vitesco Technologies.

Hassane El-Khoury, President and CEO of onsemi, commented: “This collaboration will enable Vitesco Technologies to address their customers’ demand for longer range and higher performance in electric vehicles. onsemi provides superior performance and quality, supply assurance, and manufacturing at scale of SiC technologies based on decades of experience in manufacturing power semiconductor products in high volume automotive applications.” SiC semiconductors are a pivotal technology for electrification enabling highly efficient power electronics leading to reduced charging times and longer range for electric cars.

Especially at high voltage levels such as 800V, SiC inverters are more efficient than silicon models. Since 800V is the prerequisite for fast and thus convenient high-voltage charging, SiC devices are at the beginning of a worldwide boom.
