Description

AZC199-04C is a design which includes ESD

rated diode arrays to protect high speed data

interfaces. The AZC199-04C has been specifically

designed to protect sensitive components which

are connected to data and transmission lines from

over-voltage caused by Electrostatic Discharging

(ESD).

AZC199-04C is a unique design which includes

ESD 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

ground line. The internal unique design of

clamping cell prevents over-voltage on the power

line, protecting any downstream components.

Besides, there is a back-drive protection design in

AZC199-04C for power-down mode operation.

AZC199-04C may be used to meet the ESD

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

(±15kV air, ±8kV contact discharge).
