AOZ8005FI Datasheet, PDF (1/14 Pages) Alpha & Omega Semiconductors – Ultra-Low Capacitance TVS Diode Array

AOZ8005
Ultra-Low Capacitance TVS Diode Array
General Description
The AOZ8005 is a transient voltage suppressor array
designed to protect high speed data lines such as HDMI
and Gigabit Ethernet from damaging ESD events.
This device incorporates eight surge rated, low capaci-
tance 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 AOZ8005 provides a typical line to line capacitance
of 0.47pF and low insertion loss up to 2GHz providing
greater signal integrity making it ideally suited for HDMI
1.3 applications, such as Digital TVs, DVD players,
set-top boxes and mobile computing devices.
The AOZ8005 comes in RoHS compliant, tiny SOT-23-6
and MSOP-10 packages and is rated -40°C to +85°C
junction temperature range.
The MSOP package features a flow through layout
design.
