AOZ8903
Ultra-Low Capacitance TVS Diode Array
General Description
The AOZ8903 is a transient voltage suppressor array designed to protect high speed data lines from Electro Static Discharge (ESD) and lightning.
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).
The AOZ8903 comes in RoHS compliant SOT-23 package. It is rated over a -40°C to +85°C ambient temperature range.
Features
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 Low clamping voltage .
