Low Capacitance ESD Protection Array
For High Speed Data Interfaces
Features
ESD Protect for 4 high-speed I/O channels
Provide ESD protection for each channel to
IEC 61000-4-2 (ESD) ±15kV (air), ±8kV (contact)
IEC 61000-4-4 (EFT) (5/50ns) Level-3, 20A for I/O,
40A for Power
IEC 61000-4-5 (Lightning) 4A (8/20µs)
For low operating voltage applications: 5V,
4.2V, 3.3V, 2.5V
Low capacitance : 1.0pF typical
Fast turn-on and Low clamping voltage
Array of surge rated diodes with internal
equivalent TVS diode
Small package saves board space

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
3. Video (VGA) Interface ESD Protection
For the video (VGA) interface, the exposed
lines such as Red, Green, Blue, H-Sync, V-Sync,
DDC CLK, and DDC DAT lines for plug and
monitors should be protected from the ESD
stress. The AZC099-04S also can be used for the
video (VGA) interface ESD protection. The ESD
protection scheme for video (VGA) interface is
shown in the Fig. 5. In Fig. 5, each exposed line
of video interface should connect to the ESD
protection pin of AZC099-04S. The power pin
(pin 5) of AZC099-04S just directly connected to
the VDD power supply.
When ESD voltage appears on the signal line,
the ESD pulse current will be discharged by
AZC099-04S. Therefore, all exposed lines of
video interface are complementally protected
with an AZC099-04S.
