Description
AZ2025-04S is a design which includes four
bi-directional surge rated clamping cells to
protect four power lines, or four control lines, or
four low speed data lines in an electronic
systems. The AZ2025-04S 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), Lightning, and Cable
Discharge Event (CDE).
AZ2025-04S is a unique design which includes
proprietary clamping cells in a single package.
During transient conditions, the proprietary
clamping cells prevent over-voltage on the power
lines or control/data lines, protecting any
downstream components.
AZ2025-04S is bi-directional and may be used on
lines where the signal swings above and below
ground.
AZ2025-04S may be used to meet the ESD
immunity requirements of IEC 61000-4-2, Level 4
(±15kV air, ±8kV contact discharge).
