Hi all,

I would like to know how to decide which type of ESD protection i should go with like TVS diode or MOV , varistor etc .

How do we decide ESD parameters like clamping voltage for my application

 

Generally, MOVs are less precise but can withstand large peak energy pulses, while TVSs are faster but cannot accept such a large energy. It really depends on what kind of interface you are protecting, whether it is a power supply or data line, and what kind of ESD standards do you need to pass.

 

Ok Thanks, Our product comes under IoT category and meant for USA .

So Can you please advice me what kind of ESD standard generally needed ?
Thanks in advance

If you need to comply with an ESD standard - you should know what it is, or at least where to look it up.

Most of the time its sufficient to clamp any exposed IO lines to the supply rails with protection devices.

MOV and TVS devices are normally the first line of defense in harsh environments.

Littlefuse make more than just fuses - they do a whole range of protection devices - their appnotes are an education.
