Hi,
I am looking for the units of ESD protection. At which magnitude in numbers we can say that the device has good ESD protection ?

How do you define "good"? ESD is a boring, complicated subject. It depends on your device. It depends on your environment. It depends on cost. It depends on whether you are concerned with circuit upsets only, or damage.

There are standards that you can look at (ANSI S20.20, for example).

Hello
Yes, exactly. The choice of ESD depends on your design.
Operating temperature, cost, operating voltage, dimensions ....
But to protect against shocks, what matters most is the level of protection. Level 1, Level 2, Level 3, Level 4. (The protection varies in these standards.)

Hi,

Can anyone please explain these two standards or levels, what does 200 V or 2000 V mean in ESD protection ?

ESD protection:
*HBM JESD22-A114F exceeds 2000 V
*MM JESD22-A115-A exceeds 200 V

What are the two standards, HBM and MM ?

You obviously need to educate yourself about ESD; you apparently don’t even know the fundamentals. You‘re trying to put on the roof before you’ve built the foundation.

HBM us human body model. MM is machine model.

Hi,

What is simpler than doing an internet search "ESD HBM MM"?
8 characters...

At least on the first page of the results there is wikipeda and a lot of good explanations.

When I learned electronics, there was no internet. Lucky you ... it is simple, it is for free.. so why don't you use it?
