AOZ8903

Ultra-Low Capacitance TVS Diode Array

General Description

Features

The AOZ8903 is a transient voltage suppressor array

designed to protect high speed data lines from Electro

Static Discharge (ESD) and lightning.

 ESD protection for high-speed data lines:

– IEC 61000-4-2 (ESD) ±20kV (air), ±15kV (contact)

– IEC 61000-4-5 (Lightning) 4A (8/20µs)

– IEC 61000-4-4 (EFT) 40A (5/50nS)

– Human Body Model (HBM) ±24kV

 Protects four I/O lines

This device incorporates eight surge rated, low

capacitance steering diodes and a Transient Voltage

Suppressor (TVS) in a single package. During transient

conditions, the steering diodes direct the transient to

either the positive side of the power supply line or to

ground. They may be used to meet the ESD immunity

requirements of IEC 61000-4-2, Level 4 (±15kV air,

±8kV contact discharge).

 Low clamping voltage

 Low operating voltage: 5.0V

Applications

 USB 2.0 Power and Data Line Protection

 Video Graphics Cards

The AOZ8903 comes in RoHS compliant SOT-23

package. It is rated over a -40°C to +85°C ambient

temperature range.

 Monitors and Flat Panel Displays

 Digital Video Interface (DVI)
