AMCV-0402-090-C800N-T is a form of Transient Voltage Suppressor (TVS) device, commonly referred to as a Surge Protective Device (SPD). Varistors, MOVs (Metal-Oxide Varistor) and TVS are all types of surge protective devices that protect equipment from voltage spikes. A TVS is a voltage-dependent resistor designed to protect electronics from transient overvoltages.

A TVS is a two-terminal, bi-directional device that is non-ohmic. It will conduct current when the voltage across it exceeds the breakover voltage. The current flows for a short time until the voltage reaches the rated breakover voltage. The TVS then breaks down, releasing the voltage and energy across the TVS. This breakdown causes the TVS to be destroyed, and thusly is typically not suitable for use in high-surge applications.

The AMCV-0402-090-C800N-T is an ultra-compact double-diode TVS that provides protection against both ESD (electrostatic discharge) and EFT (electrical fast transient) events. It is valid from 6.0V to 400V and has an ultra-low peak power of 370W. It also features very low capacitance and low reverse breakdown voltage of 8.0V. Additionally, the surge suppression rating of the AMCV-0402-090-C800N-T is up to 50A.

An ideal application field of the AMCV-0402-090-C800N-T is for audio/video connectors, appliances, cell phones and other consumer electronics that require transient voltage protection. The device can also protect automotive equipment from power surges and spikes, as well as overexposure to high temperatures and humidity. The AMCV-0402-090-C800N-T is also ideal for solutions which require minimized board space, such as satellite and navigation systems, as it is small in size and has a large distance between the pins.

The working principle of the AMCV-0402-090-C800N-T relies on the concept of breakdown voltage. The device consists of two symmetrically arranged avalanche diodes connected to each other in series. The junction breakdown of the diodes occurs when the voltage between the anode and the cathode exceeds the avalanche voltage, resulting in a low resistance path between the two p terms. This low resistance path dissipates the energy of the transient, protecting the device from damage due to overvoltage.

When a transient voltage spike or surge occurs, the AMCV-0402-090-C800N-T begins by clamping the voltage below the clamping voltage. Then, when the voltage exceeds the breakdown voltage, the device breaks down and clamps the voltage at its rated breakdown voltage. Once the transient has passed, the device will return to its normal state.

In conclusion, the AMCV-0402-090-C800N-T is a television-transient suppression diode designed for use in audio/video connectors, automotive equipment, appliances, consumer electronics, and other applications that require transient protection. The device works by clamping the voltage below its clamping voltage and then breaking down when the voltage exceeds its breakdown voltage. Once the transient has passed, the device will return to its normal state.
