Other pins and interfaces
All the module pins that are externally accessible on the device integrating SARA-G3 series module should
be included in the ESD immunity test since they are considered to be a port as defined in
ETSI EN 301
489-1
[16]. Depending on applicability, to satisfy ESD immunity test requirements according to ESD
category level, all the module pins that are externally accessible should be protected up to ±4 kV for
direct Contact Discharge and up to ±8 kV for Air Discharge applied to the enclosure surface.
The maximum ESD sensitivity rating of all the other pins of the module is 1 kV (Human Body Model
according to JESD22-A114). Higher protection level could be required if the related pin is externally
accessible on the application board. The following precautions are suggested to achieve higher protection
level:
A general purpose ESD protection device (e.g. EPCOS CA05P4S14THSG or EPCOS
CT0402S14AHSG varistor) should be mounted on the related line, close to accessible point
