Description

AZ4120-01F is a design which includes a

unidirectional ESD rated clamping cell to protect

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

speed data line in an electronic system. The

AZ4120-01F has been specifically designed to

protect sensitive components which are

connected to power and control lines from

over-voltage damage caused by Electrostatic

Discharging (ESD), Electrical Fast Transients

(EFT), Lightning, and Cable Discharge Event

(CDE).

AZ4120-01F 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.

AZ4120-01F may be used to meet the ESD

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

(±15kV air, ±8kV contact discharge).
