AOZ8806
Ultra-Low Capacitance TVS Diode
General Description
Features
The AOZ8806 is a transient voltage suppressor array
designed to protect high speed data lines such as HDMI,
USB 3.0, 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 twelve 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 six I/O lines
Low capacitance between I/O lines: 0.3 pF
Low clamping voltage
The AOZ8806 provides a typical line-to-line capacitance
of 0.3 pF and low insertion loss up to 6 GHz providing
greater signal integrity making it ideally suited for
HDMI 1.3, Thunderbolt, or USB 3.0 applications, such as
Digital TVs,
Low operating voltage: 5.0 V
Applications
DVD players, computing, set-top boxes and MDDI
applications in mobile computing devices.
HDMI, USB 3.0, MDDI, SATA, Thunderbolt ports
Monitors and flat panel displays
Set-top box
The AOZ8806 comes in a RoHS compliant and
Halogen free 3.3 mm x 1.3 mm x 0.4 mm 8-lead package
and is rated for -40 °C to +85 °C junction temperature
range.
