Hello, I have found here in youspice the IEC61000-4-2 simulator made by Luca Buccolini: https://youspice.com/simple-spice-esd-generator-circuit-based-on-iec61000-4-2-standard/
I’m doing a project about ESD protection on a pcb using a PCB Spark Gap. This spark gap should pass some of the IEC6100-4-2 levels.
So, basically, what I need to know if there is any way to make a component called Spark gap or if there is any equivalent electric circuit in order to place it after the IEC simulator. Then, I would place the impedance of the Device under test in order to check how many current/voltage arrives to it. These values would change in function of the gap distance.
Any help is welcome.
PD: Info about PCB Spark gaps ( really interesting ) : https://youtu.be/vfP_65gSSBU
Hi…There are a few SPICE models for gas discharge phenomena.It’s not very useful given the complexity of plasma physics, and the extreme variation in practice (breakdown voltage depends on electrode shape, rate of voltage rise, ambient temperature and humidity, UV light or other sources of ionization, surface contamination (adsorbed substances, and dust), and past history, especially where substrate breakdown occurs (carbon tracking).
