Definition of ESD
All electronic modules are equipped with large-scale integrated ICs or components. Due to
their design, these electronic elements are highly sensitive to overvoltage, and thus to any
electrostatic discharge. These electronic components are therefore specially identified as
ESDs.
Abbreviations
The following abbreviation is commonly used for electrostatic sensitive devices:
● EGB – Elektrostatisch Gefährdete Bauteile/Baugruppen (Germany)
● ESD – Electrostatic Sensitive Device (internationally recognized term)
Labeling
ESDs are labeled with the following symbol:
