Amidst heightening concerns over the global environment, initiatives to become more environmentally friendly in the fields of IT and new energy, among others, are focusing attention on power semiconductors with efficient power conversion. In this context, demand exists for MOSFETs (metal-oxide-semiconductor field-effect transistor)—the principal devices used for power conversion in semiconductors—that improve energy efficiency to a greater extent than in the past. In response, Fuji Electric is releasing the Super J-MOS series featuring its newly developed superjunction (SJ) structure, which achieves low on-resistance performance and significantly reduces energy loss.

With the release of the new series, Fuji Electric intends to contribute to the realization of a low-carbon society by improving power conversion efficiency and reducing power consumption in equipment.


  • 70% reduction in on-resistance, thereby achieving industry-leading performance in low power loss, compared to previous Fuji Electric products
  • The latest switching loss reduction technology, enabling a 14% reduction in total loss from the device, compared with previous Fuji Electric products
