Next-Gen 650 V SiC MOSFETs Improve Performance for EV Applications

White Paper Overview 

SiC MOSFETs offer advantages over silicon-based counterparts, including higher efficiency, reduced conduction and switching losses, and better thermal performance. The M3S technology, part of onsemi’s third-generation SiC MOSFETs, achieves lower specific on-resistance and superior switching performance compared to both previous onsemi generations and competitors. Advantages include:

• 31−42% lower switching energy losses
• 35% lower switching losses overall
• Reduced capacitances
• Faster switching
• Lower recovery charge and energy

With the growing demand for power density, efficiency, and thermal performance in EV systems, the M3S technology addresses key industry challenges. Coupled with the comprehensive product portfolio, onsemi’s M3S MOSFETs offer a versatile and reliable solution for high-efficiency power conversion.
