描述 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.
