onesemi has expanded its collaboration with Schaeffler to produce silicon carbide (SiC) MOSFETs from its next-generation EliteSiC product line for a brand new plug-in hybrid electrical car platform. The traction inverter, developed by Schaeffler for a worldwide automaker, makes use of onsemi’s SiC expertise to enhance power effectivity, reliability, and packaging flexibility.
Based on onsemi, the EliteSiC MOSFETs supply the bottom on-state resistance of their class, enabling increased peak energy supply and system effectivity. The units present low conduction losses and robust short-circuit robustness, permitting for a compact and thermally environment friendly inverter design. These traits assist lengthen car vary, cut back upkeep, and assist extra versatile car integration.
“The traction inverter is on the coronary heart of each electrified drivetrain, and onsemi’s EliteSiC answer performs a significant position in reaching the effectivity and efficiency targets that our buyer calls for,” stated Christopher Breitsameter, Head of Enterprise Division Controls at Schaeffler.
The partnership marks a shift from insulated-gate bipolar transistors (IGBTs) to SiC in hybrid platforms, even for cost-sensitive EV architectures.
“Our industry-leading silicon carbide semiconductor expertise delivers unmatched effectivity, thermal efficiency, and energy density—key enablers for next-generation electrical powertrain programs not just for battery electrical autos, but additionally for plug-in hybrid platforms,” stated Simon Keeton, Group President of the Energy Options Group at onsemi.
This announcement builds on a multi-year collaboration between the 2 firms—previously beneath Vitesco Applied sciences, which merged with Schaeffler in 2024—to develop high-efficiency electrical mobility options.
