AOZ8251
One-line Bidirectional TVS Diode
General Description
Features
The AOZ8251 is a one-line bidirectional transient voltage
suppressor diode designed to protect high speed data
lines and voltage sensitive electronics from high transient
conditions and ESD.
 ESD protection for high-speed data lines:
This device incorporates one bidirectional TVS diode in an
ultra-small 0201 footprint package. It may be used to
meet the ESD immunity requirements of IEC 61000-4-2,
Level 4 (±15 kV air, ±15 kV contact discharge).
 Small package saves board space
The AOZ8251 comes in an RoHS compliant package
and is rated over a -40 °C to +85 °C ambient
temperature range.
 Pb-free device
The ultra-small 0.6mm x 0.3 mm x 0.3 mm 0201 footprint
package makes the AOZ8251 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.
 Portable handheld devices
– Exceeds: IEC 61000-4-2 (ESD) ±30 kV (air),
±25 kV (contact)
– Human Body Model (HBM) ±25 kV
 Low capacitance: 8.0 pF
 Low clamping voltage
 Low operating voltage: 5.0 V
Applications
 Keypads, data lines, buttons
 Notebook computers
 Digital Cameras
 Portable GPS
 MP3 players
