    Products Detail

    STF8NK85Z Overview


    The input capacitance parameter, CI, is defined as the capacitance between the input terminals of an op amp with either input grounded, and this device's maximal input capacitance is 1870pF @ 25V.The drain current is the maximum continuous current the device can conduct, and the continuous drain current (ID) of this device is 6.7A. Drain-source breakdown voltage is the VDS at which a specified value of ID flows, with VGS=850V. And this device has 850V drain to source breakdown voltage.Turn-Off delay time is the time taken to charge the input capacitance of the device before drain current conduction can start, and its turn-off delay time is 58 ns.The gate-source voltage, VGS, of a FET transistor is the voltage that falls across the gate-source terminal of the transistor and its voltage can be 30V.By using drive voltage (10V), this device helps reduce its overall power consumption.

    STF8NK85Z Features


    a continuous drain current (ID) of 6.7A
    a drain-to-source breakdown voltage of 850V voltage
    the turn-off delay time is 58 ns
