Application example ESD0P4RFL 1 RF signal channel, anti-parallel configuration 1 protected signal line, superimposed DC voltage up to VF (diode forward volatge) I/O ESD sensitive circuit Line to ground capacitance 0.4 pF @1 GHz The protection diode should be placed very close to the location where the ESD or other transients can occur to keep loops and inductances as small as possible. Grounded pins should be connected in parallel directly to a ground plane on the board. 2.
