The PSM712 is an asymmetrical transient voltage suppressor (TVS) array, designed specically for RS-485 applicaons.
This device provides protecon against ESD, terary lightning and switching transients.
The PSM712 has a peak pulse power of 600 Was for an 8/20µs waveshape and is available in SOT-23 package con-
guraon. This device meets the IEC 61000-4-2, 61000-4-4 and IEC 61000-4-5 requirements.
Compable with IEC 61000-4-2 (ESD): Air 15kV, Contact 8kV
Compable with IEC 61000-4-4 (EFT): 40A, 5/50ns
Compable with IEC 61000-4-5 (Surge): 24A, 8/20µs - Level 2(Line-
Ground) & Level 3 (Line-Line)
600 Was Peak Pulse Power per Line(tp = 8/20µs)
