Qorvo's UJN1205K is a 1200 V, 45 mohm RDS(on) high-performance SiC normally-on JFET transistor. This series exhibits ultra-low on resistance (RDS(ON)) and gate charge (QG) allowing for low conduction and switching loss. The device normally-on characteristics with low RDS(ON) at VGS = 0 V is also ideal for current protection circuits without the need for active control, as well as for FET operation.
