AOZ8312
Low Capacitance 2.5 V TVS Diode
General Description
Features
The AOZ8312 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
–
±30 kV (air discharge) and ±30 kV (contact discharge)
– IEC 61000-4-4 (EFT) 40 A (5/50 ns)
– IEC 61000-4-5 (Lightning) 18 A
– Human Body Model (HBM) ±30 kV
This AOZ8312 incorporates twelve 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 AOZ8312 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).
Small package saves board space
Low insertion loss
Protects twelve I/O lines
Low clamping voltage
Low operating voltage: 2.5 V
Green product
The AOZ8312 comes in a Halogen Free and RoHS
compliant 3.5 mm x 2.5 mm x 0.55 mm DFN-12 package
and is rated over a -40 °C to +85 °C ambient temperature
range. The AOZ8312 is compatible with both lead free
and SnPb assembly techniques. The small size, low
capacitance and high ESD protection makes the
AOZ8312 ideal for protecting high speed video and data
communication interfaces.
