The IXFA44N25X3 is an N-channel enhancement mode MOSFET designed for switch-mode and resonant-mode power supplies, DC-DC converters, PFC circuits, and motor drives. It is packaged in a TO-263 surface-mount format with a drain tab, measuring 1.6 mm from case to lead solder point. The device has a drain-source breakdown voltage of 250 V, a continuous drain current of 44 A at 25°C, and a maximum on-resistance of 40 mΩ at 10 V gate voltage. It is avalanche-rated with an energy rating of 400 mJ and demonstrates a dv/dt capability of 50 V/ns. The thermal resistance from junction to case is 0.52 °C/W. The part meets international standard package specifications and is rated for operation from -55 °C to 150 °C junction temperature. It is RoHS compliant and features low package inductance and low gate charge.
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.
