AOZ8831A
Ultra Low Capacitance One-line
Bidirectional TVS Diode
General Description
The AOZ8831A is an ultra low capacitance one-line
bidirectional transien t voltage suppressor diode designed
to protect high speed data lines a nd voltage sensitive
electronics from high transient conditions and ESD.
This device incorporates one bidirectional TVS
diode in an
ultra-small DFN 1.0x0.6 footprint package.
It may be
used to
meet the ESD immunity requirements of IEC
61000-4-2, Level 4 (±15kV air, ±15kV contact discharge).
The AOZ8831A comes in an RoHS compliant package
and is rated over a -40 °C to +85°C am b i en t
temperature range.
The ultra-small 1 .0 x 0.6 x 0.5mm DFN p ackage makes it
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.
Features
ESD protection for high - spe e d da ta lines:
– Exceeds: IEC 61000-4-2 (ESD), ±25kV (contact)
– Human Body Model (HBM) ±25kV
Small package saves board spa ce
Ultra low capacitance: 0.30pF
Low clamping voltage
Low operating voltage: 5.0V
Pb-free device
Applications
Portable handheld devices
Keypads, data lines, buttons
Notebook computers
Digital Cameras
Portable GPS
MP3 players
