Description
AZ5725-01F 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
AZ5725-01F 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), and Cable Discharge Event
(CDE).
AZ5725-01F is a unique design which includes

Transient Voltage Suppressing Device
Tiny Pacakge for ESD/Transient Protection
Applications Information
The AZ5725-01F is designed to protect one line
against
System
ESD/EFT/Cable-Discharge
pulses by clamping it to an acceptable reference.
It provides bi-directional protection.
The usage of the AZ5725-01F 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. Since
AZ5725-01F is b-directional, these connections
can be reversed (protected line to pin 2, ground
to pin 1). In order to minimize parasitic
inductance in the board traces, all path lengths
connected to the pins of AZ5725-01F should be
kept as short as possible.
Input
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 AZ5725-01F.
Place the AZ5725-01F 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.
