    Hi there;

    In one forum told me how to check N channel mosfet but i see "strange" items with a diode for Gate protection between G and S. Is the way the same?

    About MOS transistors is the rule for MOSFET valid because when i type how to check mos transistors in google on first page i see only results with MOSFET?

    I know the following :
    short between G and S and measure resistance between D and S. Big (must) and maybe small.
    Charge with battery + G and - S and then measure small resistance in the both directions.

    Thanks in advance

    You'll get plenty of useful information if you Google "test methods for mosfets".

    A "mos transistor" is a "mosfet".
