2.1.6.1 Enhanced ESD Protection for SIM Interface
To optimize ESD protection for the SIM interface it is possible to add ESD diodes (eg.
NUP4114) to the SIM interface lines as shown in the example given in Figure 11. Please place
the ESD protection close to the SIM connector. It is suggested that the cload of diode be less
than 3pF.
The example was designed to meet ESD protection according ETSI EN 301 489-1/7: Contact
discharge: ± 4kV, air discharge: ± 8kV.
