Keywords:electronic modules  electrostatic discharge  ISO 7637-2 

Electronic equipment represents a large part of the automobiles of today. Although these electronic modules bring much more comfort and security for the vehicle user, they also bring significant concerns in terms of reliability regarding the automobile environment.

Because electronic modules are sensitive to electromagnetic interference, electrostatic discharge (ESD), and other electrical disturbances (and the automobile itself is the source of many such hazards), caution must be taken wherever electronic modules are used in the automotive environment.

Several standards have been produced to model the electrical hazards that are currently found in automobiles. As a result, manufacturers and suppliers have to consider these standards and have to add protection devices to their modules to fulfil the major obligations imposed by these standards.

For these reasons, electronic onboard modules must withstand immunity and ESD transients defined respectively by the international ISO 7637-2 and ISO 10605 standards.
