Description
AZC398-04C is a high performance and low cost
design which includes surge rated diode arrays
to protect high speed data interfaces. The
AZC398-04C family has been specifically
designed to protect sensitive components, which
are connected to data and transmission lines,
from over-voltage caused by Electrostatic
Discharging (ESD), Electrical Fast Transients
(EFT), and Lightning.
AZC398-04C is a unique design which includes
surge rated, 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 ESD bus line or to the
ground line. The internal unique design of
clamping cell prevents over-voltage on the ESD
bus line, protecting any downstream
components.
AZC398-04C may be used to meet the ESD
immunity requirements of IEC 61000-4-2, Level 4
(± 15kV air, ±8kV contact discharge).
