Design Consideration

Because of the fast rise-time of the ESD transient,

placement of ESD devices is a key design consideration.

To achieve optimal ESD suppression, the devices should be

placed on the circuit board as close to the source of the ESD

transient as possible. Install the ESD suppressors directly

behind the connector so that they are the first board-level

circuit component encountered by the ESD transient. They

are connected from signal/data line to ground.
