A Low-Capacitance ESD Protection TVS Array for High-Speed Data Interfaces from Amazon Microelectronics is in stock at distributor New Yorker Electronics.

The AZ1015-02N is used for audio interface, monitor and flat panel display, USB2.0 and SIM ports, video graphics cards and Firewire ports.

It maintains low surge clamping voltage for ESD/EOS Protection, low capacitance to keep signal integrity and offers varying integration techniques to reduce cost.

A high performance design includes surge-rated diode arrays to protect high-speed data interfaces.

The device has been specifically designed to protect sensitive components that are connected to data and transmission lines, from over-voltage caused by Electrostatic Discharging (ESD), Electrical Fast Transients (EFT) and lightning.

A unique design of clamping cell which is an equivalent TVS diode in a single package.

During transient conditions, the steering diodes direct the transient to either the power supply line or to the ground line.

The clamping cell design prevents overvoltage on the power line, protecting any downstream components.

This low-capacitance ESD Protection Array is designed to protect two data lines and power rails from transient overvoltage (such as ESD stress pulse).

When ESD voltage pulse appears on the data line, the ESD pulse current will be conducted by AZ1015-02N away from the USB controller chip, even when the pulse appears on the VBUS of the USB port.

Therefore, the data lines and VBUS of the two ports are completely protected with this device.

With regard to audio interference, the ESD pulse current will be discharged, thus completely protecting the right/left channels of the audio chip.

The AZ1015-02N may be used to meet the ESD immunity requirements of IEC 61000-4-2, Level 4 (±15kV air, ±8kV contact discharge).

As a franchise distributor for Amazing Microelectronic, New Yorker Electronics supplies Taiwan-based Amazing Microelectronics ESD products, EMI Filters, Interface ICs and Switches.
