PE4268
Product Specification
ESD Protection Circuit
Figure 18. ESD Protection Circuit
Handset products must tolerate large ESD surges
at the antenna interface without damage. The IEC
61000-4-2 standard specifies both 8 kV contact
and 16 kV air discharges that typical handsets
must survive. By itself, the PE4268 offers
protection to 1.5 kV but with the addition of two
inexpensive passive components, the switch can
meet the levels as specified in the IEC spec.
Figure 18 is the suggested solution for compliance
with the IEC standards.
