AZ1045-02F
Ultra Low Capacitance ESD Protection Array
For High Speed I/O Port
Features
ESD Protect for 2 high-speed I/O channels
Provide ESD protection for each channel to
IEC 61000-4-2, (ESD) ±15kV (air), ±10kV (contact)
Description
AZ1045-02F is a design which includes ESD
rated diode arrays to protect high speed data
interfaces. The AZ1045-02F has been
specifically designed to protect sensitive
components which are connected to data and
transmission lines from over-voltage caused by
Electrostatic Discharging (ESD).
AZ1045-02F is a unique design which includes
ESD rated, ultra low capacitance steering diodes
and a unique design of clamping cell which is an
equivalent TVS diode
in a single package. During
transient conditions, the steering diodes direct
the transient to either the internal ESD line or to
ground line. The internal unique design of
clamping cell prevents over-voltage on the
internal ESD line and on the I/O line, which is
protecting any downstream components.
AZ1045-02F may be used to meet the ESD
immunity requirements of IEC 61000-4-2, Level 4
(±15kV air,
±8kV
contact discharge).

AZ1045-02F
Ultra Low Capacitance ESD Protection Array
For High Speed I/O Port
Applications Information
A. Device Connection
The AZ1045-02F is designed to protect two
data lines from transient over-voltage (such as
ESD stress pulse). The device connection of
AZ1045-02F is shown in the Fig. 1. In Fig. 1, the
two protected data lines are connected to the
ESD protection pins (pin1, pin2) of AZ1045-02F.
The ground pin (pin3) of AZ1045-02F is a
negative reference pin. This pin should be
directly connected to the GND rail of PCB
(Printed Circuit Board). To get minimum parasitic
inductance, the path length should keep as short
as possible.
AZ1045-02F can provide protection for 2 I/O
signal lines simultaneously. If the number of I/O
signal lines is less than 2, the unused I/O pins
can be simply left as NC pins.

B. Application
AZ1045-02F is designed for protecting high
speed I/O ports from over-voltage caused by
Electrostatic Discharging (ESD). Thus, a lot of
kinds of high speed I/O ports can be the
applications of AZ1045-02F. Fig. 2 shows MHL
ESD protection by using AZ1045-02F. The
AZ1045-02F is designed for allowing the traces
to run straight through the device to simplify the
PCB layout. The best way to design the PCB
trace is using the flow through layout.
