The IXFH140N20X3 is an N-channel enhancement mode 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 packaged in a TO-247 case with a weight of 6.0 g and features an avalanche rating, low on-resistance of 9.6 mΩ at 25°C, and a maximum drain-source voltage of 200 V. The device supports a continuous drain current of 140 A and a pulsed drain current of 250 A, with a maximum junction temperature of 150°C. Thermal resistance from junction to case is 0.25 °C/W, and the gate charge totals 127 nC. It meets international standard package requirements and is rated for a transient gate-source voltage of ±30 V.
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.
