Description
AZ4212-01F 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 systems. The
AZ4212-01F has been specifically designed to
protect sensitive components which are
connected to data and transmission lines from
over-voltage caused by Electrostatic Discharging
(ESD), Electrical Fast Transients (EFT), and
Cable Discharge Event (CDE).
AZ4212-01F 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.
AZ4212-01F is bi-directional and may be used on
lines where the signal swings above and below
ground.
AZ4212-01F may be used to meet the ESD
immunity requirements of IEC 61000-4-2, Level 4
(±15kV air, ±8kV contact discharge).
