CASE
CASE
D (2)
This SiC FET device 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-247-3L package, this device exhibits ultralow gate charge and exceptional reverse recovery characteristics,
making it ideal for switching inductive loads when used with
recommended RC-snubbers, and any application requiring standard
gate drive.

Applications Information
SiC FETs are enhancement-mode power switches formed by a highvoltage 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 (RDS(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.

UnitedSiC assumes no liability whatsoever relating to the choice,

herein.
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
