Description
AZ1575-04S is a high-performance design which
includes surge rated diode arrays to protect
high-speed data interfaces. The AZ1575-04S 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.
AZ1575-04S 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.
AZ1575-04S may be used to meet the ESD
immunity requirements of IEC 61000-4-2, Level 4
(15kV air, 8kV contact discharge).
