SimCom SIM8905A User Manual page 34

high-voltage potential is always at risk of discharging to a lower potential. If this discharge path is through a
semiconductor device, it may result in destructive damage.
SIM8905A must be handled according to the ESD Association standard: ANSI/ESD S20.20-1999, Protection of
Electrical and Electronic Parts, Assemblies, and Equipment.
