The IXFK300N20X3 is an N-channel enhancement mode power MOSFET designed for high-power switching applications such as switch-mode and resonant-mode power supplies, DC-DC converters, PFC circuits, and motor drives. It is housed in a TO-264K package and rated for a drain-source voltage of 200 V with a continuous drain current of 160 A. The device has a typical on-resistance of 4 mΩ at 25°C and is avalanche rated with an energy rating of 3.5 J. It features low gate charge (375 nC), low package inductance, and a maximum junction temperature of 150°C. The thermal resistance from junction to case is 0.10 °C/W. The part meets international standard package specifications and is designed for high power density and space savings.
Developed using a charge compensation principle and proprietary process technology, these Ultra Junction MOSFETs provide the best-in-class Figure of Merit (on-resistance times gate charge), which translates into lowest conduction and switching losses. They exhibit the lowest on-state resistances in the industry. With low reverse recovery charge and time, the body diodes are capable of removing all the leftover energies during high-speed switching to avoid device failure and achieve high efficiency. Moreover, these new devices are avalanche capable and exhibit a superior dv/dt performance as well. They are robust against device failure caused by voltage spikes and accidental turn-on of parasitic bipolar transistors inherent in the MOSFET structure. As such these rugged devices require fewer snubbers and can be used in both hard and soft switching power converters.
