I have a fully qualified EMI/EMC power supply that guarantees output of 5V +/-5% when subjected to hostile EFT/surge signals. As a double precaution, I would like to add additional protection device just in case there is a over voltage. Which device or scheme is suitable?. The 5V is connected to my MCU.
1. Ferrite bead with bypass cap
2. Just bidirectional TVS smaj5.0a
3. Combination of TVS and MOV
or any other method, please suggest
