AOZ8905
Ultra-Low Capacitance TVS Diode Array
General Description
The AOZ8905 is a transient voltage suppressor array
designed to protect high speed data lines such as HDMI,
USB 2.0, MDDI, SATA, and Gigabit Ethernet from
damaging ESD events.
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.
The AOZ8905 provides a typical line to line capacitance
of 0.35pF and low insertion loss up to 3GHz providing
greater signal integrity making it ideally suited for HDMI
1.3 or USB 2.0 applications, such as Digital TVs,
DVD players, Computing, set-top boxes and MDDI
applications in mobile computing devices.
The AOZ8905 comes in RoHS compliant and halogen
free SOT23-6L package and is rated -40°C to +85°C
junction temperature range.
Features

AOZ8905
Based on the AOZ8905 SOT23-6 package design, a very
straight forward layout can be achieved. To give the TDR
an extra level of margin the traces may be compensated
to have a nominal impedance of 90throughout the
differential pair. To make the design perfect the added
capacitance of the device will have to be compensated
by the use of “Skinny Traces”. The skinny traces are a
narrow stripe line acting to lower the parasitic
capacitance on the differential stripe line. The
differential impedance of the USB 3.0 transmission line
becomes well centered to 90. A layout EM field
simulator is recommended before fabrication to insure a
perfect stripe line. With careful layout and placement of
the device, the AOZ8905 can protect the USB 3.0 data
line effectively and safely and meet the ESD immunity
requirements of the IEC61000-4-2, level 4, ±15kV air
discharge, ±8kV contact discharge.
