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

 

The attached pdf should answer part of your question.

 

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.

Great reference. Thanks!

 

Thank you ,that reference was exactly what i needed.
