AOZ8304
Low Capacitance 3.3V TVS Diode Array
General Description
Features
The AOZ8304 is a transient voltage suppressor array
designed to protect high speed data lines from ESD and
lightning.
● ESD protection for high-speed data lines:
– IEC 61000-4-2, level 4 (ESD) immunity test
– ±24kV (air discharge) and ±24kV (contact discharge)
– IEC 61000-4-4 (EFT) 40A (5/50ns)
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. They may be used to meet the
ESD immunity requirements of IEC 61000-4-2, Level 4
and IEC 61000-4-5. The TVS diodes provide effective
suppression of ESD voltages: ±24kV (air discharge) and
±24kV (contact discharge).
– IEC 61000-4-5 (Lightning) 25A
– Human Body Model (HBM) ±30kV
● Small package saves board space
● Low insertion loss
● Protects four I/O lines
● Low clamping voltage
● Low operating voltage: 3.3V
● Green product
The AOZ8304 comes in a Halogen Free and RoHS
compliant DFN-10 2.6mm x 2.6mm package and is rated
over a -40°C to +85°C ambient temperature range. The
AOZ8304 is compatible with both lead free and SnPb
assembly techniques. The small size, low capacitance
and high ESD protection makes it ideal for protecting
high speed video and data communication interfaces.
