Good circuit board layout is critical for the suppression of fast rise-time transients such as ESD.The following guidelines are recommended (Refer to application note Sl99.01 for more detailed information): •Place the TVS near the input terminals or connectors to restrict transient coupling. •Minimize the path length between the TVS and the protected line. •Minimize all conductive loops including power and ground loops. •The ESD transient return path toground should be kept as short as possible. •Never run critical signals near board edges •Use ground planes whenever possib|e. http://www.SeCoSGmbH.com 16-Oct.-2008 Rev.
