Abstract: In the latest few months of last year, more and more publications report about ESD requirements for an EPA "Class 0". What does this mean? Means the semiconductor producer “0” voltage in the area or in the EPA. The standards ANSI/ESD S20.20-2014 and the IEC standard IEC 61340-5-1 does not describe this point. According to this classification, class “0Z” means a maximum electrostatic voltage of 50 volt in the EPA. Class “0A” means an electrostatic voltage between 50 and 125 volt. The typical requirement for an EPA according to the ESD standards (ANSI and IEC) is a maximum electrostatic voltage of 100 volt. At today, the requirements for the electronic industry are higher than for other industries. Most of the EPAs meet these requirements.
