Electrostatic sensitive devices
Definition
All electronic modules are equipped with large-scale integrated ICs or compo-
nents. 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

S
ensitive
D
evices. This is also the international abbreviation for such devices.
Electrostatic sensitive devices are identified by the following symbol:
Figure B-1 Electrostatic sensitive devices
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.
