RFMW Expert Product Pick: UG4SC075005L8S 750V SiC Combo-FET

What made you select the Qorvo UG4SC075005L8S as a featured product? What value and differentiation does this product offer?

Qorvo’s UG4SC075005L8S “Combo-FET” combines a 750V SiC JFET and a Low Voltage Si MOSFET in a single TOLL package. This innovative design enables users to create circuitry with a normally-off switch while benefiting from the features of a normally-on SiC JFET. These advantages include ultra-low on-resistance (RDS(on)), which minimizes conduction losses, and the exceptional robustness of a simplified JFET device structure, making it well-suited for high-energy switching in circuit protection applications.

For switch-mode power conversion, this device offers separate access to the JFET and MOSFET gates, enhancing speed control and facilitating paralleling multiple devices.
