SCT3105KR
1200V, 24A, 4-pin THD, Trench-structure, Silicon-carbide (SiC) MOSFET

SCT3105KR is an SiC MOSFET that features a trench gate structure optimized for electric vehicle charging stations, solar power inverters, and server power supplies 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.
