I'm designing a circuit which has Voltage regulator(IC), current source(IC), resistor, capacitors, LED, reed switch and capacitor. It has to survive 10KV ESD event.
My question is: 1) What components should I protect with spark gap and TVS diode? 2) How can I achieve this? Use both(spark gap and TVS diode) or just one? 3) Any other things I should consider in my design for the protection?
Update: ESD standard/model to follow : IEC 61000-4-2
Circuit has to survive the ESD event at all the points in the circuit including at the connector where it receives the power.
Thanks in advance.
