Description

AZ4233-01F is a design which includes one

bi-directional ESD rated clamping cell to protect

one power line, or one control line, or one low

speed data line in an electronic system. The

AZ4233-01F has been specifically designed to

protect sensitive components which are

connected to data and transmission lines from

over-voltage damage caused by Electrostatic

Discharging (ESD), Electrical Fast Transients

(EFT), and Cable Discharge Event (CDE).

AZ4233-01F is a unique design which includes

proprietary clamping cell in a single package.

During transient conditions, the proprietary

clamping cell prevents over-voltage on the power

line or control/data lines, protecting any

downstream components.

AZ4233-01F is bi-directional and may be used on

lines where the signal swings above and below

ground.

AZ4233-01F may be used to meet the ESD

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

(±15kV air, ±8kV contact discharge).
