描述 Description

AZ4920-01F is a design which includes a

uni-directional surge rated clamping cell to

protect one power line, one control line, or one

low-speed data line in an electronic system. The

AZ4920-01F 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 Transient

(EFT), Lightning, and Cable Discharge Event

(CDE).

AZ4920-01F 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, control lines, or data lines, protecting any

downstream component.

AZ4920-01F may be used to meet the ESD

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

(±15kV air, ±8kV contact discharge).
