No license, express or implied, to any intellectual connected in series. The silicon MOSFET serves as the control unit property rights is granted within this document. while the SiC JFET provides high voltage blocking in the off state. This combination of devices in a single package provides compatibility with UnitedSiC assumes no liability whatsoever relating to the choice, standard gate drivers and offers superior performance in terms of low selection or use of the UnitedSiC products and services described on-resistance (R herein. DS(on)), output capacitance (Coss), gate charge (QG), and reverse recovery charge (Qrr) leading to low conduction and switching losses. The SiC FETs also provide excellent reverse conduction capability eliminating the need for an external anti-parallel diode. Like other high performance power switches, proper PCB layout design to minimize circuit parasitics is strongly recommended due to the high dv/dt and di/dt rates. An external gate resistor is recommended when the FET is working in the diode mode in order to achieve the optimum reverse recovery performance.
