Circuit board layout

Circuit board layout is a critical design step in the suppression of ESD induced transients.

The following guidelines are recommended :

●

The ESDA25LY should be placed as close as possible to the input terminals or

connectors.

●

The path length between the ESD suppressor and the protected line should be

minimized

●

All conductive loops, including power and ground loops should be minimized

●

The ESD transient return path to ground should be kept as short as possible.

●

Ground planes should be used whenever possible.
