Applications Information
Device Connection Options
The SM series is designed to protect one
36 volts.Connection options are as follows:
•Unidirectional:Data lines are connected to pin1
Circuit Board Layout Recommendations for suppres-
sion 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):
•Place the TVS near the input terminals or connec-
•Minimize the path length between the TVS and the
•Minimize all conductive loops including power and

and Pin 3 is connected to ground.For best
results,this pin should be connected directly to a
