AOZ8105
Ultra-Low Capacitance TVS Diode Array
General Description
Features
The AOZ8105 is a transient voltage suppressor array
designed to protect high speed data lines such as HDMI
and Gigabit Ethernet from damaging ESD events.
● ESD protection for high-speed data lines:
– IEC 61000-4-2, level 4 (ESD) immunity test
– ±30kV (air discharge) and ±24kV (contact discharge)
– IEC 61000-4-5 (Lightning) 3A (8/20µs)
– Human Body Model (HBM) ±24kV
● Array of surge rated diodes with internal TVS diode
● Small package saves board space
● Protects four I/O lines
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 AOZ8105 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 applications, such as Digital TVs, DVD players,
set-top boxes and mobile computing devices.
● Low capacitance between I/O lines: 0.35pF
● Low clamping voltage
● Low operating voltage: 5.0V
Applications
The AOZ8105 comes in RoHS compliant, tiny SOT-23-6
package and is rated -40°C to +85°C junction tempera-
ture range.
