Description
AZ6225-01F is a design which includes one
bi-directional surge rated clamping cell to protect
one power line, or one control line, or one low
speed data line in an electronic systems. The
AZ6225-01F 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).

AZ6225-01F
Low Voltage Transient Voltage Suppressing Device
0402 DFN Package for ESD/Surge Protection
Applications Information
The AZ6225-01F is designed to protect one line
against System ESD/EFT/Lightning pulses by
clamping it to an acceptable reference. It
provides bi-directional protection.
The usage of the AZ6225-01F is shown in Fig. 1.
Protected line, such as data line, control line, or
power line, is connected at pin 1. The pin 2 is
connected to a ground plane on the board. In
order to minimize parasitic inductance in the
board traces, all path lengths connected to the
pins of AZ6225-01F should be kept as short as
possible.
In order to obtain enough suppression of ESD
induced transient, good circuit board is critical.
Thus, the following guidelines are recommended:
Minimize the path length between the
protected lines and the AZ6225-01F.
Place the AZ6225-01F near the input
terminals or connectors to restrict transient
coupling.
The ESD current return path to ground
should be kept as short as possible.
Use ground planes whenever possible.
NEVER route critical signals near board
edges and near the lines which the ESD
transient easily injects to.
