What Is Esd Protection? It Is The Secret To Safe Electronics Assembly
The ESD is applied on the box. The voltage of the ESD can be as high as 15kV (whatever the value it does not really change the problem) An IC can tolerate a voltage on its pins equal to 80V and 6V5. Here is my drawing as a summary : So when the circuit is isolated from the metallic box, it seems relatively simple to protect all the circuits.
