AOZ8224 Four-line Bi-directional TVS Diode  General Description
AOZ8224
Four-line Bi-directional TVS Diode
General Description
Features
The AOZ8224 is a four-line bi-directional transient
voltage suppressor diode designed to protect voltage
sensitive electronics from high transient conditions
and ESD.
 ESD protection for high-speed data lines:
This device incorporates eight TVS diodes in a small
SOT-23 package. It may be used to meet the ESD
immunity requirements of IEC 61000-4-2, Level 4
(± 15 kV air, ± 8 kV contact discharge).
The AOZ8224 comes in a SOT-23 package and is rated
over a -40 °C to +85 °C ambient temperature range.
The small SOT-23 package makes the AOZ8224 ideal for
applications where PCB space is a premium. The small
size and high ESD protection is ideal for protecting
voltage sensitive electronics from high transient
conditions and ESD.
– Exceeds IEC 61000-4-2 (ESD) ± 30 kV (air),
± 30 kV (contact)
– Human Body Model (HBM) ± 30 kV
– IEC 61000-4-5 (Lightning) 5 A (8/20 µs)
 IEC 61000-4-4 (EFT) ± 40A
 Small package saves board space
 Low insertion loss
 Low clamping voltage
 Low operating voltages: 5.0 V
Applications
 Portable handheld devices
 Keypads, data lines, buttons
 Notebook computers
 Digital cameras
 Portable GPS
 MP3 players
