onsemi, a global leader in intelligent power and sensing technologies, has announced the expansion of its long-standing collaboration with motion technology company Schaeffler. The two companies are partnering on a new design win that integrates onsemi’s next-generation EliteSiC silicon carbide MOSFETs into a high-performance traction inverter for a major global automaker’s latest plug-in hybrid electric vehicle (PHEV) platform.
onsemi’s EliteSiC solution delivers exceptionally low conduction losses and industry-leading short-circuit robustness. These attributes enable a compact, thermally efficient inverter design that improves energy conversion, extends vehicle range, and enhances overall system reliability.
- Longer driving range, enabled by higher energy conversion efficiency
- Enhanced reliability, for consistent operation with lower maintenance
- Optimized form factor, allowing greater flexibility in vehicle design
“The traction inverter is at the heart of every electrified drivetrain, and onsemi’s EliteSiC solution plays a vital role in achieving the efficiency and performance targets that our customer demands,” said Christopher Breitsameter, Head of Business Division Controls at Schaeffler.
As automakers increasingly prioritize energy efficiency and performance, the industry is turning to more advanced hybrid architectures even in cost-sensitive EV platforms, a market traditionally dominated by insulated-gate bipolar transistors (IGBTs). onsemi’s role as an industry leader in silicon carbide positions it at the forefront of this transition, enabling Schaeffler to deliver an EV system that meets stringent performance and packaging requirements.
“As the exclusive silicon carbide supplier for this program, onsemi continues to strengthen its position as a trusted innovation partner for leading global automotive players,” said Simon Keeton, Group President, Power Solutions Group, onsemi. “Our industry-leading silicon carbide semiconductor technology delivers unmatched efficiency, thermal performance, and power density—key enablers for next-generation electric powertrain systems not only for battery electric vehicles, but also for plug-in hybrid platforms.”
This new milestone builds on the existing long-term collaboration between onsemi and Schaeffler (formerly Vitesco Technologies), extending the companies’ multi-year collaboration and reinforcing their shared commitment to delivering high-efficiency electric mobility solutions.
