1200V-35mW SiC Cascode Rev. A, January 2019 DATASHEET Description United Silicon Carbide s cascode products co-package its high- UF3C120040K4S performance F3 SiC fast JFETs with a cascode optimized MOSFET to produce the only standard gate drive SiC device in the market today. This series exhibits very fast switching using a 4-terminal TO-247- package and the best reverse recovery characteristics of any device of similar ratings. These devices are excellent for switching inductive loads, and any application requiring standard gate drive.
