AOZ8809ADI
Ultra-Low Capacitance TVS Diode
General Description
Features
The AOZ8809ADI is a transient voltage suppressor array
designed to protect high speed data lines such as HDMI
1.4/2.0, USB 3.0/3.1, MDDI, SATA, and Gigabit Ethernet
from damaging ESD events.
ESD protection for high-speed data lines:
– IEC 61000-4-2, level 4 (ESD) immunity test
– Air discharge: ±15 kV; contact discharge: ±15 kV
– IEC61000-4-4 (EFT) 40 A (5/50 ns)
– IEC61000-4-5 (Lightning) 4 A (8/20 μs)
– Human Body Model (HBM) ±24 kV
This device incorporates eight surge rated, low
capacitance steering diodes and a TVS in a single
package. During transient conditions, the steering diodes
direct the transient to either the positive side of the power
supply line or to ground.
Array of surge rated diodes with internal TVS diode
Small package saves board space
Protects four I/O lines
Low capacitance between I/O lines: 0.25 pF
Low clamping voltage
The AOZ8809ADI provides
a
typical line-to-line
capacitance of 0.25 pF and low insertion loss up to 6GHz
providing greater signal integrity making it ideally suited
for HDMI 1.4/2.0 or USB 3.0/3.1 applications, such as
Digital TVs, DVD players, computing, set-top boxes and
MDDI applications in mobile computing devices.
Low operating voltage: 3.3V, 5.0 V
Applications
HDMI 1.4/2.0, USB 3.0/3.1, MDDI, SATA ports
Monitors and flat panel displays
Set-top box
The AOZ8809ADI comes in a RoHS compliant and
Halogen Free 2.5 mm x 1.0 mm x 0.55 mm DFN-10
package and is rated for -40°C to +85°C junction
temperature range.
