Description
AZ1243-04F is a high performance design which
includes ESD rated diode arrays to protect high
speed data interfaces. The AZ1243-04F has
been specifically designed to protect sensitive
components, which are connected to data and
transmission lines, from over-voltage caused by
Electrostatic Discharging (ESD), Lightning, and
Cable Discharge Event (CDE).
AZ1243-04F is a unique design which includes
ESD rated, ultra low capacitance steering diodes
and a unique design of clamping cell which is an
equivalent TVS diode in a single package. During
transient conditions, the steering diodes direct
the transient to either the internal ESD line or to
ground line. The internal unique design of
clamping cell prevents over-voltage on the
internal ESD line and on the I/O line, which is
protecting any downstream components.
AZ1243-04F may be used to meet the ESD
immunity requirements of IEC 61000-4-2, Level 4
(±15kV air, ±8kV contact discharge).
