AOZ8212
Two-line Bi-directional TVS Diode
General Description
The AOZ8212 is a two-line bi-directional transient
voltage suppressor diode designed to protect voltage
sensitive electronics from high transient conditions
and ESD.
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).
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.
