IXFK44N55Q Overview
As a result of avalanche breakdown, energy applied to the MOSFET is called avalanche energy, and the avalanche energy rating is 2500 mJ.A device's maximum input capacitance is 6400pF @ 25V, but its input capacitance parameter, CI, is measured as the capacitance between the input terminals of the device with either input grounded.Its continuous drain current is 44A for this device. Drain current refers to the capacity of the device to conduct continuous current.Single MOSFETs transistor is the voltage at which VDS flows at a specified ID value, wSingle MOSFETs transistorh VGS=550V, and this device has a drain-to-source breakdown voltage of 550V voltage.A device's turn-off delay time is the amount of time it takes to charge its input capacitance before drain current conduction can begin, which is 75 ns.Its maximum pulsed drain current is 176A, which is also its maximum rating peak drainage current.Before drain current conduction begins, the device's input capacitance must be charged, so the delay time is 30 ns.Generally, the gate-source voltage (VGS) of a FET transistor is the voltage across its gate-source terminal, which is 20V.For normal operation, maintain the DS breakdown voltage above 550 V.To operate this transistor, you need to apply a 550V drain to source voltage (Vdss).This device uses no drive voltage (10V) to reduce its overall power consumption.
