SOT-23 Outline Dimensions
components which are connected to data and transmission lines against ESD.
It clamps the voltage just above the logic level supply for positive transients,
and to a diode drop below ground for negative transients. It can also work as
bidirectionnal suppressor by connecting only pin1 and 2.
IEC61000-4-2 Level 4
MIL STD 883c - Method 3015-6 Class 3(Human Body Model)
the line interface withstands only with 2kV ESD surges.
