    Does ESD has a performance index,like figure of merit?

    Thank you!

    It has. The standards for ESD sets voltage levels and source characteristics (such as human body model (HBM) or machine model (MM) ). Both the model and the voltage level may be specified in the product's datasheet.

    charge device mode(CDM) is the other ESD performance index besides the HBM and MM

    Re: Does ESD has a performance index,like figure of merit?

    The figure of merit is the voltage*model that the device
    withstands. Some newer standards even require that it
    withstand multiple strikes. There are "Class" bins that
    group ESD susceptibility; if you're a manufacturing dude
    you may simply want to know that the assembly floor's
    ESD threat level is lower than the lowest "Class" part to
    be handled, not each one's specific HBM rating.

    And of course any / all of this could have been yours
    for the Googling, while you were waiting for answers
    to be served.

    Beware of MM model. Doesnt actually model anything ... has been dropped by JEDEC standards some years ago.

    Industry standards employ HBM and CDM nowadays.
