General Description
AZC099-04S is a high performance and low cost design which includes surge rated
diode arrays to protect high speed data interfaces. The AZC099-04S 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.
AZC099-04S 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.
AZC099-04S may be used to meet the ESD immunity requirements of IEC 61000-4-2,
Level 4 (± 15kV air, ±8kV contact discharge).
