Silicon Carbide FET TO2474L Package UJ4C075044K4S 750V 44mW Optimized for Switch Mode Power Supplies
UnitedSiC UJ4C075044K4S 750V SiC FET
Product Overview
The UnitedSiC UJ4C075044K4S is a 750V, 44mW G4 Silicon Carbide (SiC) FET designed for high-performance power applications. This device utilizes a unique 'cascode' circuit configuration, combining a normally-on SiC JFET with a Si MOSFET to create a normally-off SiC FET. Its standard gate-drive characteristics make it a direct 'drop-in replacement' for Si IGBTs, Si FETs, SiC MOSFETs, and Si superjunction devices. The UJ4C075044K4S is available in a TO-247-4L package, offering ultra-low gate charge, exceptional reverse recovery characteristics, and low intrinsic capacitance. These features make it ideal for switching inductive loads and applications requiring standard gate drive, such as EV charging, switch-mode power supplies, and PV inverters.
