Description
AZ1145-04F is a design which includes ESD
rated diode arrays to protect high-speed data
interfaces. The AZ1145-04F has been
specifically designed to protect sensitive
components which are connected to data and
transmission lines from over-voltage damage
caused by Electrostatic Discharging (ESD),
Electrical Fast Transients (EFT), Lightning, and
Cable Discharge Event (CDE).
AZ1145-04F 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.
AZ1145-04F may be used to meet the ESD
immunity requirements of IEC 61000-4-2, Level 4
(15kV air, 8kV contact discharge).
