Hi,
I need to design an Ethernet Surge Protector. I have fond one simple and cheep circuit solution on the web:
https://tyconpower.com/products/files/TP-ESP-100-POE_Surge_Protector_Spec_Sheet.pdf
Can anyone advise how to select varistor Z1 and Z2? Why they are different?
Some diodes i.e. D1 and D7 are connected in parallel. Can anybody explain why?
