Qorvo / UnitedSiC UJ4C/SC 750V Gen 4 SiC FETs
UnitedSiC / Qorvo UJ4C/SC 750V Gen 4 SiC FETs are a high-performance series delivering industry-best performance Figures of Merit that lower conduction losses and increase efficiency at higher speed, all while improving overall cost-effectiveness. Available in 5.4mΩ to 60mΩ options, the Gen 4 series is based on a unique cascode configuration, where a high-performance SiC JFET is co-packaged with a cascode optimized Si-MOSFET to produce a standard gate drive SiC device. The standard gate-drive characteristics of the UJ4C/SC 750V FETs allow for "drop-in replacement" functionality. Designers can significantly enhance system performance without the need to change gate drive voltage by replacing existing Si IGBTs, Si FETs, SiC FETs, or Si super-junction devices with the UnitedSiC / Qorvo UJ4C/SC FETs.
The UnitedSiC / Qorvo UJ4C/SC 750V Gen 4 SiC FETs are offered in a three-lead TO247-3L package, a four-lead TO-247-4 package featuring a Kelvin Gate connection, or a MO-229 package. The Kelvin source design of the TO-247-4 package significantly reduces switching losses and gate ringing. The MO-229 package delivers faster switching and cleaner gate waveforms.
