With the intention of protecting the input of the charger against ESD and overvoltage, I would like to know if it is recommended to use the TVS and the Zener on the same circuit, if so, what would be the configuration?
The intention is to meet the requirement of IEC 61000-4-2, but also to protect the system if an unsuspecting person connects a charger of 12V or more, instead of 5V.
The Reverse Standoff Voltage of the chosen TVS is VRWM = 5V, and the Clamp Voltage for the TLP 16A graph is Vc = 11V.
The zener has not been chosen yet.
