TVS diodes, or transient voltage suppressors, are a type of voltage-regulating component that offers overvoltage protection for electrical systems. The ATV02W190B-HF is one such device, designed to provide up to 28A of energy dissipation and breakdown voltage of up to 190v for high-frequency applications. This article will discuss the fields of application and working principle of the ATV02W190B-HF.

The ATV02W190B-HF is ideal for applications requiring a high-frequency transient voltage suppressor. It is a common choice in a variety of applications, such as protection of systems against lightning strikes, overvoltage issues, and surges. It is also quite popular in automotive systems, aerospace and military applications, as it provides excellent protection against extreme voltages occurring infrequently in these fields.

The ATV02W190B-HF\'s working principle is relatively simple. The device uses a nonlinear junction diode to ‘short’ the voltage across an access device, such as a capacitor or transformer line. When the line\'s voltage rises beyond the breakdown voltage, the diode will conduct and the excess voltage will be diverted, dissipating the energy and preventing potential damage to the device. The device is also designed to have a fast reset time, allowing it to quickly reset to its breakdown voltage and provide protection once more.

The ATV02W190B-HF\'s breakdown voltage of 190v is one of the highest available on the market. It is also relatively small, measuring less than 1 square millimeter, meaning it can be comfortably fitted to even the smallest of devices. Additionally, the device includes an integrated thermal-resistant protection layer, allowing it to operate within an extended temperature range of -55°C to 125°C. These features make it an ideal choice for high-frequency applications that require quick response times and the ability to handle extreme voltages.

In conclusion, the ATV02W190B-HF is one of the most popular transient voltage suppressors on the market, offering up to 28A of energy dissipation and breakdown voltage of up to 190v for high-frequency applications. It is well-suited to a variety of sectors such as automotive, aerospace, and military, due to its reliable protection against lightning strikes, overvoltages, and surges. Its small size and integrated thermal-resistant layer make it an excellent choice for devices requiring quick response times and the ability to handle extreme voltages.
