ROHM and onsemi launch new SiC MOSFETs for higher efficiency in EVs, solar, and energy systems.

ROHM has started mass production of its SCT40xxDLL silicon carbide MOSFETs in TOLL packages, offering 39% better thermal performance than standard TO-263-7L packages, with up to 750V voltage rating and on-resistances from 13mΩ to 65mΩ. Designed for compact, high-power applications like AI servers, energy storage, and solar inverters, the devices feature a 26% smaller footprint and 2.3mm height. Available through distributors starting September 2025, simulation models are also provided. Meanwhile, onsemi launched 650V and 950V ElieSiC MOSFETs in T2Pak top-cool packages, enabling direct heatsink coupling for improved cooling, reduced temperatures, and higher power density in electric vehicles, solar, and energy storage systems.
