UJ3N120070K3S

70mW - 1200V SiC Normally-On JFET | UJ3N120070K3S Datasheet Description CASE D (2) CASE United Silicon Carbide, Inc offers the high-performance G3 SiC normallyon JFET transistors. 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 cascode operation.
