In a strategic move that underscores the rapid evolution of electric mobility, onsemi and Schaeffler have announced an expanded collaboration to develop a cutting-edge plug-in hybrid electric vehicle (PHEV) platform powered by onsemi’s EliteSiC silicon carbide technology.
At the heart of this partnership lies a next-generation traction inverter designed by Schaeffler, which will be integrated into a leading global automaker’s PHEV system. This inverter leverages onsemi’s EliteSiC MOSFETs, known for their:
- Lower conduction losses, boosting energy efficiency
- Superior short-circuit robustness, enhancing system reliability
- Industry-leading low on-state resistance, enabling peak power performance
These features allow for a compact and thermally efficient design, translating into longer driving ranges, reduced maintenance, and greater flexibility in vehicle architecture.
Traditionally, hybrid platforms have relied on insulated-gate bipolar transistors (IGBTs). However, as automakers push for higher energy efficiency and performance, silicon carbide (SiC) is emerging as the preferred choice—even in cost-sensitive segments. onsemi’s EliteSiC technology positions the company as a key enabler of this transition, offering unmatched power density and thermal performance.
This milestone builds on a multi-year collaboration between onsemi and Schaeffler (formerly Vitesco Technologies), reinforcing their shared commitment to high-efficiency electric mobility solutions. As the exclusive silicon carbide supplier for this program, onsemi continues to cement its role as a trusted innovation partner for global automotive leaders.
With the automotive industry at a pivotal moment, this collaboration exemplifies how advanced semiconductor technologies can unlock new possibilities in electrified drivetrains. By combining Schaeffler’s motion expertise with onsemi’s power innovation, the partnership is poised to deliver next-gen hybrid systems that meet the demands of both performance and sustainability.arket positions but also signals a broader industry shift toward cleaner, more efficient energy technologies.
