Directive for handling electrostatically sensitive
devices (ESD)
C.1 What does ESD mean?
Definition
All electronic modules are equipped with large-scale integrated chips or components. Due to
technological reasons, these electronic components can be damaged easily by overvoltage
and thus discharge from static electricity.
The acronym ESD has become the established designation for such Electrostatically
Sensitive Devices. The ESD designation is used internationally to refer to electrostatically
sensitive devices.
Electrostatically sensitive devices are marked with the following symbol:
!
Caution
Electrostatically sensitive devices can be destroyed even by voltages which are far below
the human perceptive limit. These voltages already occur when you touch a component or
electrical connections of a module, without being electrostatically discharged. The damage
resulting at a module due to an overvoltage is in most cases not detected immediately, but
only noticed after a longer period of operation.
