Insights
onsemi's EliteSiC design win with Schaeffler strengthens its SiC position in the growing PHEV market, boosting long-term revenue prospects.
This expanded collaboration between onsemi and Schaeffler represents a significant commercial milestone for onsemi's silicon carbide (SiC) business. The design win for a leading global automaker's PHEV platform validates onsemi's strategic investment in next-generation EliteSiC technology and expands its footprint in the hybrid electric vehicle market.
The technical advantages highlighted are substantial. onsemi's EliteSiC MOSFETs offer lower conduction losses and superior short-circuit robustness, with the company claiming the lowest on-state resistance for highest peak power in its class. These aren't just incremental improvements—they translate to meaningful consumer benefits: longer driving range, enhanced reliability, and optimized form factor for vehicle design flexibility.
What's particularly noteworthy is onsemi securing an exclusive supplier position for this program. This suggests the company has established a technical edge over competitors in a segment traditionally dominated by cheaper IGBT technology. As the automotive industry pushes toward more sophisticated hybrid architectures even in cost-sensitive platforms, onsemi is positioning itself at the forefront of this technology transition.
This design win reinforces onsemi's strategy of focusing on high-value power semiconductor applications following its transformation from the broader ON Semiconductor identity. The multi-year collaboration with Schaeffler (formerly Vitesco Technologies) indicates a stable, long-term revenue stream from this partnership that should continue to expand as PHEV adoption grows alongside fully electric vehicles in the global automotive market.
Traction inverter solution will use onsemi’s next-generation EliteSiC to enable longer driving range and enhanced reliability for plug-in hybrid EVs
SCOTTSDALE, Ariz., July 24, 2025 (GLOBE NEWSWIRE) -- onsemi (Nasdaq: ON) today announced an expanded collaboration with leading motion technology company Schaeffler through a new design win that leverages onsemi’s next-generation EliteSiC product line of silicon carbide MOSFETs. The onsemi solution will power the Schaeffler traction inverter for a leading global automaker’s cutting-edge plug-in hybrid electric vehicle (PHEV) platform.
onsemi’s EliteSiC technology offers significantly lower conduction losses and superior short-circuit robustness, enabling a compact, thermally efficient inverter design that enhances overall system performance. This silicon carbide-based solution offers the lowest on-state resistance to provide highest peak power compared to other SiC solutions in its class. These benefits allow Schaeffler to deliver an innovative traction inverter system that achieves measurable benefits to the end customer, including:
- 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.
