AOZ8804A
Ultra-Low Capacitance TVS Diode
General Description
Features
The AOZ8804A 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.
z ESD protection for high-speed data lines:
– IEC 61000-4-2, level 4 (ESD) immunity test
– Air discharge: ±15kV; contact discharge: ±15kV
– IEC61000-4-4 (EFT) 40A (5/50nS)
– IEC61000-4-5 (Lightning) 2.5A (8/20µS)
– Human Body Model (HBM) ±24kV
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.
z Array of surge rated diodes with internal TVS diode
z Small package saves board space
z Protects four I/O lines
z Low capacitance between I/O lines: 0.3pF
z Low clamping voltage
The AOZ8804A provides a typical line to line capacitance
of 0.3pF and low insertion loss up to 6GHz providing
greater signal integrity making it ideally suited for HDMI
1.3 or USB 3.0 applications, such as Digital TVs,
DVD players, Computing, set-top boxes and MDDI
applications in mobile computing devices.
z Low operating voltage: 5.0V
Applications
z HDMI, USB 3.0, MDDI, SATA ports
z Monitors and flat panel displays
z Set-top box
The AOZ8804A comes in a RoHS compliant and
Halogen Free 2.5mm x 1.0mm x 0.55mm DFN-10
package and is rated -40°C to +85°C junction
temperature range.
z Video graphics cards
z Digital Video Interface (DVI)
z Notebook computers
