onsemi Silicon Carbide (SiC) Combo JFETs | UG4SC075005L8S
Silicon Carbide (SiC) Combo JFET - EliteSiC, 5.0 mohm, 750V, TOLL
The UG4SC075005L8S "Combo-JFET" integrates both a 750V SiC JFET and a Low Voltage Si MOSFET into a single TOLL package. This innovative approach allows users to create circuitry that would enable a normally-off switch while leveraging the benefits of a normally-on SiC JFET. These benefits include ultra-low on-resistance (RDS(on)) to minimize conduction losses and the exceptional robustness characteristic of a simplified JFET device structure, making it capable of handling the high-energy switching required in circuit protection applications. For switch-mode power conversion application, this device provides separate access to the JFET and MOSFET gates for improved speed control and ease of paralleling multiple devices.
