Description
AZC399-04S is a high performance and low cost
design which includes surge rated diode arrays
to protect high speed data interfaces. The
AZC399-04S 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.
AZC399-04S 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 power supply line or to
the ground line. The internal unique design of
clamping cell prevents over-voltage on the power
line, protecting any downstream components.
AZC399-04S may be used to meet the ESD
immunity requirements of IEC 61000-4-2, Level 4
(± 15kV air, ±8kV contact discharge).
One AZC399-04S can be used to replace 4
BAV99 devices in a 5V application or a lower
than 5V application.
