Description

AZ3028-04P is a design which includes

bi-directional surge rated clamping cells to

protect two differential high speed data-line pairs

in an electronic systems. The AZ3028-04P has

been specifically designed to protect sensitive

components which are connected to the

differential line pairs from over-voltage damage

and latch-up caused by Electrostatic Discharging

(ESD), Electrical Fast Transients (EFT),

Lightning, and Cable Discharge Event (CDE).

AZ3028-04P is a unique design which includes

proprietary clamping cells in a single package.

During transient conditions, the proprietary

clamping cells provide low clamping voltages to

minimize the stress on the protected

components.

AZ3028-04P is bi-directional and may be used on

lines where the signal swings above and below

ground.

AZ3028-04P may be used to meet the ESD

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

(±15kV air, ±8kV contact discharge).
