Description

AZ1243-04F is a high performance design which

includes ESD rated diode arrays to protect high

speed data interfaces. The AZ1243-04F has

been specifically designed to protect sensitive

components, which are connected to data and

transmission lines, from over-voltage caused by

Electrostatic Discharging (ESD), Lightning, and

Cable Discharge Event (CDE).

AZ1243-04F is a unique design which includes

ESD rated, ultra 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 internal ESD line or to

ground line. The internal unique design of

clamping cell prevents over-voltage on the

internal ESD line and on the I/O line, which is

protecting any downstream components.

AZ1243-04F may be used to meet the ESD

immunity requirements of IEC 61000-4-2, Level 4

(±15kV air, ±8kV contact discharge).
