    Products Detail

    STB40N20 Overview


    A device's maximal input capacitance is 2500pF @ 25V, which is defined as the capacitance between its input terminals with either input grounded.This device's continuous drain current (ID) is 40A, which represents the maximum continuous current it can conduct.In this device, the drain-source breakdown voltage is 200V and the drain-source breakdown voltage is the VDS at which a specified value of ID flows.Its turn-off delay time is 74 ns, which is the time to charge the device's input capacitance before drain current conduction begins.In terms of pulsed drain current, it has a maximum of 160A, which is its maximum rated peak drain current.Input capacitance charging takes time before drain current conduction begins, so the turn-on delay time is 20 ns.Gate-source voltage, or VGS, is the voltage across a FET transistor's gate-source terminal, and can be 20V volts.This device reduces its overall power consumption by using drive voltage (10V).

    STB40N20 Features


    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.
