B.1 ESD definition
What does ESD mean?
All electronic modules are equipped with highly integrated modules or components. Because
of the technology used, these electronic components are very sensitive to overvoltages and
thus to discharge of static electricity.
The acronym ESD has become the established designation for such Electrostatic Sensitive
Devices. The ESD designation is used internationally to refer to electrostatic sensitive
devices.
Electrostatic sensitive devices are identified by the following symbol:

Caution
Electrostatic sensitive devices can be irreparably damaged by voltages that are far lower
than anything a person can perceive. These voltages occur if you touch a component or the
electrical connection of a module without having previously discharged any static from your
body. Any damage that occurs to a module as a result of overvoltage is generally not
recognized immediately and only comes to light after the equipment has been operating for
some time.
