Hi, I want to add some basic surge protection on a PCB used to rectify the mains for use in a project.
I understand that I could use a TVS between L and N (after the fuse), but when I look up the parts, they all have a number of voltage ratings which can vary widely on the one part. (min/max breakdown voltage, clamping voltage, etc)
What voltage rating do I need to look for for protecting the circuit with a mains input of 220V AC ??
