onsemi, Schaeffler Partner on New EliteSiC PHEV Platform

onsemi, global industry experts in silicon carbide power semiconductors, have announced the expansion of their ongoing collaboration with motion technology company Schaeffler to supply next-generation silicon carbide MOSFETs for a new plug-in hybrid electric vehicle (PHEV) platform.

The EliteSiC technology from onsemi will be integrated into Schaeffler’s traction inverter system for a major global automotive manufacturer.

The new inverter platform is engineered to support longer electric driving range, enhanced reliability, and a more compact form factor. These benefits are enabled by improved energy conversion efficiency, reduced thermal and electrical stress on components, and a smaller footprint that allows for increased flexibility in vehicle integration. The result is a system optimized to meet stringent performance, durability, and packaging requirements in modern PHEV architectures.

onsemi’s EliteSiC MOSFET technology offers lower conduction losses and improved energy handling during transient events, allowing for higher power density and reduced thermal overhead in inverter designs. These performance characteristics enable compact, thermally efficient systems capable of maintaining stable operation across a wide range of load and environmental conditions.

“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 shifting toward wide-bandgap semiconductor platforms, even in cost-sensitive vehicle segments that have traditionally relied on insulated-gate bipolar transistors (IGBTs). onsemi’s extensive expertise in silicon carbide places it at the forefront of this transition, supporting Schaeffler’s efforts to meet evolving system-level expectations for PHEVs.

“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 a long-standing relationship between onsemi and Schaeffler (formerly Vitesco Technologies), extending a multi-year collaboration focused on advancing high-efficiency power electronics for hybrid and electric mobility platforms.
