The ESD/Arrays protection devices is based on the principle of voltage clamping , it can suppress transient voltage in a very safe range, these protecting sensitive components in the circuit from high voltage static electricity and surge damage, it complies with:

   IEC61000-4-2/ESD  Contact 8KV,Air 15KV

   IEC61000-4-4/FET  40A,5/50ns

   IEC61000-4-5/Lighting 24A, 8/20us
