UF3C SiC FETs UnitedSiC / Qorvo UF3C High-Performance SiC FETs are cascode Silicon Carbide (SiC) products that co-package high-performance G3 SiC JFETs with a cascode-optimized Si MOSFET to produce a standard gate drive SiC device. This series exhibits ultra-low gate charge and is excellent for switching inductive loads and applications requiring a standard gate drive. The UnitedSiC / Qorvo UF3C SiC FETs are available in 650V, 1200V, and 1700V versions and are offered in D2PAK-3, D2PAK-7, D2PAK-7L, TO-247-3L, TO-247-4L, and TO-220-3L packages.
