EMI Bites: One of the ways to deal with Electrostatic Discharge? Think about diverting the energy.
The problem with ESD is that if you focus on electron flow instead of energy flow, and how the fields store, couple, and carry the energy, you are going to face issues that seem like Black Magic.
So, how can we handle this?
Consider the ESD event as a high-frequency pulse.
One effective approach is to use transient voltage suppressors (TVS diodes) to shunt the ESD energy away from sensitive components.
This allows to redirect the energy away from your circuit and to channel it through a safe path.
It's a simple and sometimes inexpensive fix that we can implement at the system level, but also at the design level.
