AOZ8251ADI
Single Channel Bidirectional TVS Diode
General Description
Features
The AOZ8251ADI is an one-line bidirectional transient
voltage suppressor diode designed to protect data lines
and voltage sensitive electronics from high transient
conditions and ESD.
ESD protection for high-speed data lines:
– Exceeds: IEC 61000-4-2 (ESD) ±20 kV (air),
±20 kV (contact)
– Human Body Model (HBM) ±25 kV
Small package saves board space
Capacitance: 10 pF
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).
Low clamping voltage
Low operating voltage: 3.3 V, 5 V
Pb-free device
The AOZ8251ADI comes in an RoHS compliant package
and is rated over a -40°C to +85°C ambient temperature
range.
Applications
Portable handheld devices
Keypads, data lines, buttons
Notebook computers
Digital cameras
The ultra-small 0.62 mm x 0.32 mm x 0.3 mm 0201
footprint package makes the AOZ8251ADI 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.
