TVS (transient voltage suppressors) diodes, also known as surge suppressors, are devices that protect sensitive electronic components from prolonged exposure to excessive voltage. The PESD2ETH-ADX application field and working principle are perfect examples of a TVS diode in use. This diode is a 2-channel ultra low capacitance ESD protection device specifically designed for high speed communication protocols such as Ethernet and USB that are susceptible to radio frequency interference (RFI).

The PESD2ETH-ADX is designed to provide up to 10kV ESD (Electrostatic Discharge) protection to Ethernet and USB systems. It is also designed to protect against voltage droop, overshoot, and inrush current. The device is housed in a 3mmx3mm TDFN-10L package that is RoHS compliant and has UL flammability-rating of UL 94V-0. It operates in temperatures ranging between -40C to +85C.

The PESD2ETH-ADX works using Gas Discharge Tube (GDT) technology. It utilizes two GDTs connected in parallel to a high voltage IC to provide superior protection from ESD events. When the device is exposed to ESD, the GDTs act as a surge conductor and divert the current away from the protected circuit. The energy from the ESD event is then absorbed by the GDTs, thus providing protection for the sensitive circuit elements.

The PESD2ETH-ADX features a dual-channel design that permits parallel protection of signal lines. The device also features an adjustable discharge voltage indicator, which gives the user an indication of ESD events. This feature is especially useful for monitoring board-level ESD protection performance, which helps prevent performance degradation caused by excessive ESD.

The PESD2ETH-ADX is a versatile ESD protection device that can be applied in many applications. It is commonly used in automotive systems, communication systems, and consumer electronics to protect sensitive components from ESD events. It can also be used in medical and industrial applications since it has no limitation on surge operating frequency. This device is also suitable for industrial automation technology because its low stray capacitance ensures reliable and noise-free data transfer.

The PESD2ETH-ADX is a highly efficient ESD protection solution that offers superior performance. With its dual-channel design, adjustable discharge voltage indicator, and a wide operating temperature range, this device is an ideal choice for a wide range of applications. It has a proven track record of providing reliable and effective ESD protection, and it is compliant with all major safety and communication protocols.
