AOZ8841 Ultra Low Capacitance One-line Bidirectional TVS Diode
AOZ8841
Ultra Low Capacitance One-line
Bidirectional TVS Diode
General Description
Features
The AOZ8841 is an ultra low capacitance one-line
bidirectional transient voltage suppressor diode designed
to protect high speed data lines and voltage sensitive
electronics from high transient conditions and ESD.
 ESD protection for high-speed data lines:
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 (±15kV air, ±15kV contact discharge).
 Ultra low capacitance: 0.30pF
– Exceeds: IEC 61000-4-2 (ESD), ±25kV (contact)
– Human Body Model (HBM) ±25kV
 Small package saves board space
 Low clamping voltage
 Low operating voltage: 5.0V
 Pb-free device
The AOZ8841 comes in an RoHS compliant package
and is rated over a -40°C to +85°C ambient
temperature range.
The ultra-small 1.0 x 0.6 x 0.5mm DFN package 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.
Applications
 Portable handheld devices
 Keypads, data lines, buttons
 Notebook computers
 Digital Cameras
 Portable GPS
 MP3 players

Notes:
1. Dimensions and tolerancing conform to ASME Y14.5-2009.
2. All dimensions are in milliteters.
3. “e” represents the terminal grid pitch.
4. N isthe total number of terminals.
5. A visual index feature must be located within the hatched area. Typical index feature (chamfer) must be located on the edge
