CASE
CASE D (1)
Silicon Carbide (SiC) Cascode JFET EliteSiC, Power N-Channel, TO-247-4L, 1200 V, 70 mohm
Rev. B, January 2025
Description
The UJ3C120070K4S is a 1200V, 70mW G3 SiC FET. It is based on a unique ‘cascode’ circuit configuration, in which a normally-on SiC JFET is co-packaged with a Si MOSFET to produce a normally-off SiC FET device. The device’s standard gate-drive characteristics allows for a true “drop-in replacement” to Si IGBTs, Si FETs, SiC MOSFETs or Si superjunction devices. Available in the TO-247-4L package, this device exhibits ultra-low gate charge and exceptional reverse recovery characteristics, making it ideal for switching inductive loads and any application requiring standard gate drive.
