Circuit board layout and protection device placement:
Circuit board layout is critical for suppression of ESD transients.
The following guidelines are recommended:
1. Place the protection devices as close to the input terminal or connector as possible.
2. The path length between the protection device and protected line should be minimized.
3. Keep parallel signal pats to a minimum.
4. Avoid running protection conductors in parallel with unprotected conductor.
5. Minimize all printed-circuit board conductive loops including power and ground loops.
6. minimize the length of the transient return path to ground.
7. Avoid using shared transient return paths to common ground point.
8. Ground planes should be used whenever possible. For multilayer printed-circuit boards, use
ground vias
