Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

onsemi has announced the expansion of its collaboration with leading drive technology company Schaeffler. The two parties have adopted onsemi's next-generation silicon carbide MOSFET EliteSiC product series in a new design winning project. onsemi's solution will be integrated into Schaeffler's main drive inverter and used in the advanced plug-in hybrid electric vehicle (PHEV) platform of a globally leading automaker.

onsemi's EliteSiC technology features significantly reduced conduction losses and outstanding short-circuit resistance, enabling compact and highly heat-dissipating inverter designs and thereby enhancing overall system performance. Compared with other SiC solutions in the same type of products, this silicon carbide-based solution features industry-leading ultra-low on-resistance and can provide higher peak power. These advantages have enabled Schaeffler to develop innovative main drive inverter systems, bringing significant benefits to end customers, including:

Higher energy conversion efficiency enables longer driving range

Higher reliability ensures stable operation and reduces maintenance requirements

The optimized external dimensions make the overall vehicle design more flexible

Christopher Breitsameter, the global head of Schaeffler's Control Business Unit, said: "The main drive inverter is at the core of every electrified drive system, and onsemi's EliteSiC solution plays a crucial role in achieving the energy efficiency and performance targets required by customers."

As automakers increasingly emphasize energy efficiency and performance, the industry is transforming towards more advanced hybrid architectures, even on the cost-sensitive electric vehicle platforms previously dominated by insulated gate bipolar transistors (IGBTs). As a leader in the silicon carbide field, onsemi is leading this technological transformation and helping Schaeffler develop electric vehicle systems that simultaneously meet the demanding performance requirements and packaging specifications.

As the exclusive silicon carbide supplier for this project, onsemi continues to consolidate its position as a trusted innovation partner for the world's leading automakers. Simon Keeton, president of onsemi's Power Solutions Business Group, said, "Our industry-leading silicon carbide semiconductor technology offers superior energy efficiency, heat dissipation performance and power density, all of which are key drivers for the next-generation electric powertrain systems, not only for pure electric vehicles but also for plug-in hybrid platforms."

This new milestone is based on the long-term cooperation between onsemi and Schaeffler (which took over the original partnership after the acquisition of Vitesco Technologies). It not only continues the strategic collaboration between the two sides over the years but also further strengthens their joint commitment to providing efficient electric mobility solutions.
