Description
AZC099-04S is a high performance and low cost
design which includes surge rated diode arrays
to protect high speed data interfaces. The
AZC099-04S family 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 Lightning.
AZC099-04S is a unique design which includes
surge rated, 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 power supply line or to
the ground line. The internal unique design of
clamping cell prevents over-voltage on the power
line, protecting any downstream components.

AZC099-04S
Low Capacitance ESD Protection Array
For High Speed Data Interfaces
B. Device Connection
The AZC099-04S is designed to protect four
data lines and power rails from transient
over-voltage (such as ESD stress pulse). The
device connection of AZC099-04S is shown in
the Fig. 2. In Fig. 2, the four protected data lines
are connected to the ESD protection pins (pin1,
pin3, pin4, and pin6) of AZC099-04S. The ground
pin (pin2) of AZC099-04S 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. In addition, the
power pin (pin 5) of AZC099-04S is a positive
reference pin. This pin should directly connect to
the VDD rail of PCB. When pin 5 of AZC099-04S
is connected to the VDD rail, the leakage current
of ESD protection pin of AZC099-04S becomes
very small. Because the pin 5 of AZC099-04S is
directly connected to VDD rail, the VDD rail also
can be protected by the power-rail ESD clamped
circuit (not shown) of AZC099-04S.
AZC099-04S can provide protection for 4 I/O
signal lines simultaneously. If the number of I/O
signal lines is less than 4, the unused I/O pins
can be simply left as NC pins.
In some cases, systems are not allowed
to be reset or restart after the ESD stress
directly applying at the I/O-port connector.
Under this situation, in order to enhance the
sustainable ESD Level, a 0.1µF chip capacitor
can be added between the VDD and GND rails.
The place of this chip capacitor should be as
close as possible to the AZC099-04S.
