Applications Information
Disclaimer
SiC cascodes are enhancement-mode power switches formed by a high-voltage SiC depletion-mode JFET and a low-voltage silicon
MOSFET connected in series. The silicon MOSFET serves as the control unit while the SiC JFET provides high voltage blocking in the
off state. This combination of devices in a single package provides compatibility with standard gate drivers and offers superior
performance in terms of low on-resistance (R
DS(on)
), output capacitance (Coss), gate charge (Qg), and reverse recovery charge (Qrr)
leading to low conduction and switching losses. The SiC cascodes 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 cascode is working in the diode mode in order
to achieve the optimum reverse recovery performance. For more information on cascode operation, see www.unitedsic.com.
