4.6 Electrostatic Discharge
The module is not protected against Electrostatic Discharge (ESD) in general. Consequently,
it is subject to ESD handling precautions that typically apply to ESD sensitive components.
Proper ESD handling and packaging procedures must be applied throughout the processing,
handling and operation of any application that incorporates a ALAS5V module.
Special ESD protection provided on ALAS5V:
BATT+: Inductor/capacitor
An example for an enhanced ESD protection for the SIM interface is shown in Section 2.1.8.
The remaining interfaces of ALAS5V with the exception of the antenna interface are not acces-
sible to the user of the final product (since they are installed within the device) and are therefore
only protected according to the ANSI/ESDA/JEDEC JS-001-2011 requirements.
ALAS5V has been tested according to the following standards. Electrostatic values can be
gathered from the following table.
Note: The values may vary with the individual application design. For example, it matters
whether or not the application platform is grounded over external devices like a computer or
other equipment.
4.7 Reliability Characteristics
