    Products Detail

    STW40N20 Overview


    When a voltage exceeds breakdown voltage of a MOSFET, breakdown phenomena occurs and current flows. It's called ?Avalanche break down?, and the energy applied to the MOSFET is called avalanche energy, and the avalanche energy rating (Eas) is 230 mJ.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 2500pF @ 25V.The drain current is the maximum continuous current the device can conduct, and the continuous drain current (ID) of this device is 40A. Drain-source breakdown voltage is the VDS at which a specified value of ID flows, with VGS=200V. And this device has 200V 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 74 ns.IDM is the maximum rated peak drain current for a power MOSFET, and its maximal pulsed drain current is 160A.Turn-on delay time is the time taken to charge the input capacitance of the device before drain current conduction can start, and its delay time is 20 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 20V.By using drive voltage (10V), this device helps reduce its overall power consumption.

    STW40N20 Features


    the avalanche energy rating (Eas) is 230 mJ
    a continuous drain current (ID) of 40A
    a drain-to-source breakdown voltage of 200V voltage
    the turn-off delay time is 74 ns
    based on its rated peak drain current 160A.
