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).
