AOZ8802A
Ultra-Low Capacitance TVS Diode Array
General Description
Features
The AOZ8802A is a transient voltage suppressor array
designed to protect high speed data lines such as HDMI,
MDDI, USB, 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
z Array of surge rated diodes with internal TVS diode
z Small package saves board space
z Protects two I/O lines
This device incorporates four 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 AOZ8802A 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 applications, such as Digital TVs, DVD players,
set-top boxes and USB applications in mobile
computing devices.
z Low capacitance between I/O lines: 0.3pF
z Low clamping voltage
z Low operating voltage: 5.0V
Applications
z USB, MDDI, SATA ports
z Monitors and flat panel displays
z Set-top box
The AOZ8802A comes in a RoHS compliant and Halogen
Free 1.6mm x 1.0mm x 0.55mm DFN-6 package and is
rated -40°C to +85°C junction temperature range.
