AOZ8302
Two-line High Current Surge TVS Diodes
General Description
Features
The AOZ8302 is a high current surge transient voltages
suppressor diode designed to protect voltage sensitive
electronics from high current surge and ESD.
 ESD and high current surge protection:
This device incorporates two high current surge 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 (±15kV air, ±8kV contact discharge).
The AOZ8302 comes in an RoHS compliant SOT-23
package and is rated over a -40°C to +85°C ambient
temperature range.
The small SOT-23 package makes it ideal for
applications where PCB space is a premium. The small
size and high ESD protection makes it ideal for protecting
voltage sensitive electronics from high transient
conditions and ESD.

AOZ8302CI-12 (12V version):
– Exceeds: IEC 61000-4-2 (ESD) ±30kV (air),
±30kV (contact)
– Human Body Model (HBM) ±30kV
– IEC 61000-4-5 (Lightning) 24A (8/20µs)
 Small package saves board space
 IEC 61000-4-4 (EFT) ±40A

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.
