Externally generated ESD pulses are introduced through the Audio jacks (headphone, microphone, RCA-type plugs, etc.) and travel through the connector onto the system board. Once on the board, they will propagate down the signal lines toward the integrated circuits(IC). Most ICs are designed with 2,000V of internal ESD protection. It is not uncommon to

The application of spark gaps on audio jack for ESD protection Abstract: ESD strikes can be suppressed by placing ESD protection devices along ESD current paths. As primary ESD protection on PCBs, spark gaps are cheap and take little space, but the breakdown voltage is not low enough and the lag time can be too long to protect the circuit.
