描述 Description

AZ1213-04F is a high-performance design which

includes surge rated diode arrays to protect

high-speed data interfaces. The AZ1213-04F has

been specifically designed to protect sensitive

components, which are connected to data and

transmission lines, from over-voltage caused by

Electrostatic Discharging (ESD), Electrical Fast

Transients (EFT), and Lightning.

AZ1213-04F 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 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.

AZ1213-04F may be used to meet the ESD

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

(?15kV air, ?8kV contact discharge).
