    Hello Everyone,
    Is there ant rule of thumb as to when to use a TVS diode and when to use a Zener?
    Is it a trade off between transient voltage suppression and voltage regulation ?Is level of voltage a factor in choosing between these two?

    Thanks,
    AK

    you use zenners when you want regulation, tvs when you want spike supression. they are made a little different, the tvs is capable of a greater surge current, and the zenner, better voltage breadown precision.
