AOZ8308
Low Capacitance 2.5 V TVS Diode
General Description
The AOZ8308 is a transient voltage suppressor array
designed to protect high speed data lines from ESD and
lightning.
Features
ESD protection for high-speed data lines:
– IEC 61000-4-2, level 4 (ESD) immunity test
This AOZ8308 incorporates eight 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 AOZ8308
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:
±30 kV (air discharge) and ±30 kV (contact discharge).
–
±30 kV (air discharge) and ±30 kV (contact discharge)
– IEC 61000-4-4 (EFT) 40 A (5/50 ns)
– IEC 61000-4-5 (Lightning) 25 A
– Human Body Model (HBM) ±30 kV
Protects four I/O lines
Low clamping voltage
Low operating voltage: 2.5 V
Applications
The AOZ8308 comes in a Halogen Free and RoHS
compliant SO-8 package and is rated over a -40 °C to
+85 °C ambient temperature range. The AOZ8308 is
compatible with both lead free and SnPb assembly
techniques. The small size, low capacitance and high
ESD protection makes the AOZ8308 ideal for protecting
high speed video and data communication interfaces.
