650V, 70A, 4-pin THD, Trench-structure, Silicon-carbide (SiC) MOSFET

SCT3030AR is an SiC MOSFET featuring a trench gate structure optimized for server power supplies, motor drives, solar power inverters, and EV charging stations requiring high efficiency. A new 4-pin package is used that separates the power and driver source terminals, making it possible to maximize high-speed switching performance. This improves turn ON loss in particular, and as a result, the total turn ON and turn OFF losses can be reduced by as much as 35% compared with the conventional 3-pin package (TO-247N).

A pioneer and industry leader in SiC technology, ROHM was the first supplier to mass produce trench-type MOSFETs that further improve efficiency while reducing power consumption over existing SiC MOSFETs.
