    I am trying to use an IGBT, IRG4PC40UDPbF, to drive a motor however in the ON state it seems to have very high impedance approx 40 kOhm despite me putting 20 V on the gate.
    Any ideas what I might be doing wrong or what I should test?

    Thanks in advance

    Can you supply a diagram of how its connected and how you are measuring the resistance.
    Thanks Adam
