I am getting confused in selecting
TVS diode for Ethernet Interface.
Should I connect one
bidirectional TVS diode across a pair (one pin connecting to D+ and other to D-)? I think if transient is coupled to the Ethernet cable, then the two wires of a pair will be having same transient and it doesn't make any sense to connect a bidirectional diode across a pair.
Should I connect one TVS diode for each wire of the pair (other end of the diode connected to
Ground)? Should it be bidirectional or unidirectional?
