Circuit board layout

ESDA25LY

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.
