AOZ8251
One-line Bidirectional TVS Diode
General Description
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.
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).
The AOZ8251 comes in an RoHS compliant package
and is rated over a -40 °C to +85 °C ambient
temperature range.
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.
