AOZ8211
0ne-line TVS Diode
General Description
The AOZ8211 is a one-line transient voltage suppressor
diode designed to protect voltage sensitive electronics
from high transient conditions and ESD.
This device incorporates one TVS diode in an ultra-small
DFN 1.0 mm x 0.6 mm package. During transient
conditions, the one-line TVS diode directs the transient
to ground. It may be used to meet the ESD immunity
requirements of IEC 61000-4-2, Level 4 (±15 kV air,
±8 kV contact discharge).
The AOZ8211 comes in an RoHS compliant package
and is rated over a -40 °C to +85 °C ambient temperature
range.
The ultra-small 1.0 mm x 0.6 mm x 0.5 mm DFN package
makes the AOZ8211 ideal for applications where PCB
space is at a premium. The small size and high ESD
protection makes the AOZ8211 ideal for protecting
voltage sensitive electronics from high transient
conditions and ESD.
