Nexperia launches 1200V SiC MOSFETs with top-side cooling for thermal efficiency

Nexperia is addressing the critical thermal bottleneck in high-density power conversion where traditional bottom-side cooling through the PCB limits performance. By offering a 3kW potential increase in power handling, these MOSFETs enable more compact and efficient power systems essential for AI data centers and 800V EV architectures. This launch intensifies the technical race among top-tier SiC players like Wolfspeed and Infineon, who are prioritizing advanced packaging to maximize wide-bandgap efficiency. Watch for adoption rates in automotive onboard chargers and industrial motor drives to signal a broader industry shift toward top-side cooling as a standard for high-voltage power management.

The SiC power semiconductor market is undergoing rapid expansion, with Mordor Intelligence projecting it will grow from $3.41 billion in 2026 to $10.26 billion by 2031. This growth is heavily concentrated, with five major companies—Infineon, STMicroelectronics, Wolfspeed, onsemi, and ROHM—controlling over 90% of global revenue as of 2024. Competition has sharpened around manufacturing scalability and performance metrics; notably, per Wolfspeed (June 2026), its fifth-generation SiC MOSFETs recently achieved a 27% reduction in specific on-resistance compared to existing 1200V solutions.

This high-stakes environment is further complicated by geopolitical disruptions facing Nexperia itself. Per Sourceability (November 2025) and subsequent reports in January 2026, the company underwent a structural split into Dutch and Chinese entities following Dutch government intervention. This splintering has previously caused volatility in the automotive supply chain and led to warnings regarding the authenticity and qualification of components processed at specific sites. Despite these corporate challenges, Nexperia continues to leverage long-term technological partnerships, such as its 2023 collaboration with Mitsubishi Electric, to integrate high-voltage SiC technology into its discrete power device portfolio.
