AOZ8212
Two-line Bi-directional TVS Diode
General Description
Features
The AOZ8212 is a two-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:
AOZ8212CI-05L
– Exceeds: IEC 61000-4-2 (ESD) ± 30 kV (air),
± 30 kV (contact)
– Human Body Model (HBM) ± 30 kV
This device incorporates two 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).
– IEC 61000-4-5 (Lightning) 9 A (8/20 µs)
AOZ8212CI-12
The AOZ8212 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 AOZ8212 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)
AOZ8212CI-24
– Exceeds: IEC 61000-4-2 (ESD) ± 18 kV (air),
± 15 kV (contact)
– Human Body Model (HBM) ± 15 kV
– IEC 61000-4-5 (Lightning) 2.5A (8/20 µs)
Applications
 Small package saves board space
 Portable handheld devices
 IEC 61000-4-4 (EFT) ± 40A
 Keypads, data lines, buttons
 Low insertion loss
 Notebook computers
 Low clamping voltage
 Digital Cameras
 Low operating voltages: 5 V, 12 V, 24 V
 Portable GPS
 MP3 players

Notes:
1. All dimensions are in millimeters.
2. Controlling dimension is millimeter, converted inch dimensions are not necessarily exact.
3. Dimension D does not include mold flash, protrusions or gate burrs. Mold flash, protrusions or gate burrs shall not exceed 0.25mm per end.
Dimension E1 does not include interlead flash or protrusion. Interlead flash or protrusion shall not exceed 0.25mm per side.
4. The package top may be smaller than the package bottom. Dimensions D and E1 are determined at the outermost extremes of the plastic
body exclusive of mold flash, tie bar burrs, gate burrs and interlead flash, but including any mismatch between the top and bottom of the
plastic body.
5. Follow JEDEC TO-236HAA.
