AQ3130-01ETG is a unidirectional, bi-directional, and low capacitance transient voltage suppressor (TVS), which is designed to protect high speed data interface equipment such as USB ports and HDMI ports. This TVS diode device can clamps transient voltage up to 30V even at Ipp of more than 8A. It is capable of continuous protection from ESD, surges and hot-plugs for all USB generations.

This TVS diode device is an important component in many electronic systems, as it prevents the particular electronic equipment from being damaged by voltage transients. It has a symmetrical bidirectional and ultra-low capacitance structure which combines an integrated and precise ESD protection with excellent overvoltage protection capability. This feature also enables the traditional guard-ring structure to be omitted, resulting in a significant area/die size reduction.

The AQ3130-01ETG is manufactured in a small DFN-6 package with pick and place friendly and JEDEC compliant pad footprint. This highly integrated structure is well suited for application in industrial control systems, automotive systems, computers and peripherals, communications systems, and consumer electronics. Its low clamping voltage, fast response time, and ultra-low capacitance can protect sensitive electronics from electrical overstress (EOS) caused by EFT, lightning, or high-speed AC signals.

The main working principle of this TVS diode is to clamp the over-voltage surge transient which is above the standby voltage\'s level. The device works like a classic zener diode which will allow current to flow in one direction and also hold off voltage beyond a certain point. This is achieved by allowing the large electrical energy of the transient voltage to be dissipated as heat in the silicon junction, without the need for any external components.

When the voltage exceeds the breakdown threshold of the device, a clamping action takes place and the diode’s voltage is held steady. This prevents the dangerous overvoltage signals from reaching the sensitive components of the device that may damage them. The diode is designed to withstand high surge currents and can be used to protect circuits with a wide voltage range. This makes it ideal for a variety of applications such as telecommunications, data transfer, consumer electronics, and automotive.

In conclusion, the AQ3130-01ETG is a unidirectional, bi-directional, and low capacitance TVS diode which provides superior protection against ESD, surges and hot-plugs in USB and HDMI ports. It is suitable for high speed data interface applications in a wide range of industries, thanks to its low clamping voltage, fast response time and ultra-low capacitance characteristics. This highly integrated structure is well suited for industrial, automotive, computer, consumer electronics and communications applications.
