What does ESD mean?
All electronic modules are equipped with highly integrated modules or components. Based
on their design, these electronic components are highly sensitive to overvoltage and thus to
discharge of static electricity.
The electrostatic sensitive components/modules are commonly referred to as ESD devices.
You can also find the commonly used international designation ESD for electrostatic
sensitive device.
Electrostatic sensitive modules are identified by the following symbol:
Caution
Electrostatic sensitive devices may be destroyed by voltages and energies that are
undetectable to a human. Voltages of this kind occur as soon as a component or an
assembly is touched by a person who is not grounded against static electricity. The damage
to a module as a result of overvoltage cannot usually be detected immediately. It may only
become apparent after a long period of operation.
