Description

AZ4A21-01B is a design which includes a

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

AZ4A21-01B has been specifically designed to

protect sensitive components which are

connected to power and control lines from

over-voltage damage and latch-up caused by

Electrostatic Discharging (ESD), Electrical Fast

Transients (EFT), and Cable Discharge Event

(CDE).

AZ4A21-01B 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.

AZ4A21-01B is bi-directional and may be

used on lines where the signal swings above and

below ground.

AZ4A21-01B may be used to meet the ESD

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

(±15kV air, ±8kV contact discharge).
