    Default Re: Protection Circuit

    10-33K resistors should be fine(depending on zener leakage current).
    D1, D3, D4 protect MOSFET's gate from over voltage. Usually Vgs is +-20V, so any zener between 5 and 15V should be ok.
    Vmax should be Vd2+Gate Threshold Voltage of Q2(usually 1-3V).
    MOSFETs depends on your max voltage and current.
