Santa Clara, CA and Kyoto, Japan, Dec. 04, 2025 (GLOBE NEWSWIRE) -- ROHM Semiconductor today announced they have begun mass production of the SCT40xxDLL series of SiC MOSFETs in TOLL (TO-Leadless) packages. Compared to conventional packages (TO-263-7L) with equivalent voltage ratings and on-resistance, these new packages offer approximately 39% improved thermal performance. This enables high-power handling despite their compact size and low profile. It is ideal for industrial equipment such as server power supplies and ESS (Energy Storage Systems) where the power density is increasing, and low-profile components are required to enable miniaturized product design. In applications like AI servers and compact PV inverters, the trend toward higher power ratings is occurring simultaneously with the contradictory demand for miniaturization, requiring power MOSFETs to achieve higher power density. Particularly in totem pole PFC circuits for slim power supplies, often called “the pizza b
