Device Connection Options
The SM series is designed to protect one unidirectional data or l/O lines operating at 5 to 36 volts.Connection options are as follows: EUnidirectional:Data lines are connected to pin1 and Pin 3 is connected to ground.For best results,this pin should be connected directly to a ground plane on the board.The path lengh should be kept as short as possible to minimize parasitic inductance. Circuit Board Layout Recommendations for suppression of ESD. 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): EPlace the TVS near the input terminals or connectors to restrict transient coupling. EMinimize the path length between the TVS and the protected line. EMinimize all conductive loops including power and ground loops. EThe ESD transient return path toground should be kept as short as possible. ENever run critical signals near board edges EUse ground planes whenever possib|e.
