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).
