TVS - Diodes comprise a class of components that are designed to protect users, their systems, and downstream components from electrical transients and surges of higher energies. Firstly, SA58AHE3/73 is one of the most popular TVS - Diodes among the TVS diode family, which provides great protection against sudden electrical disturbances.

The application field of SA58AHE3/73 is specifically designed for environments which feature industrial electrical control equipment. And the most specific purpose of it is to protect against over-voltages and surges, which may damage other circuit elements. As widely used, this special type of TVS diode mainly applied in a variety of electronic appliances, such as monitors, monitors, TV Receivers, DVD players, satellite TV receivers, personal computers, etc.

It\'s also known that the SA58AHE3/73 features excellent over-current, over-voltage and surge protection characteristics. The most salient features of SA58AHE3/73 are their low forward voltage drops at rated current, protecting the down-line components from unwanted high-current and reducing overall power consumption. In addition, it has a maximum peak pulse current of 4500A and a breakdown voltage of 5V.

How this diode works? To better understand, its working theory can be divided into three stages: the first stage is the axial-symmetric ionization, which starts at the peak of the pulse voltage; the second stage is the plasma resonance stage, where the current is discharged in the form of plasma; the third stage is the avalanche breakdown stage, where the avalanche current is higher than the ionization current and the breakdown voltage is reached. This process helps ensure that the diode not only has a high level of surge protection but also a low operating voltage which increases its efficiency.

As a conclusion, SA58AHE3/73 is one of the most popular and cost effective type of TVS - Diodes currently in use. It can provide protection against sudden electrical disturbances, as well as reduce down-line components from unwanted high-current and reduce overall power consumption. Also, the three-stage process of this diode ensures it has a high level of surge protection, as well as low operating voltage, making it a more efficient diode.
