TVS - Diodes

The SA20A-E3/73 is a type of TVS - Diode often used to provide protection against voltage surges and electrical spikes. This form of protection is important to ensure the safety and longevity of many electrical systems and delicate electronic components. The following article details the application field and working principle of this specific type of TVS - Diodes.

Application Field

The SA20A-E3/73 is most commonly used in power installations, such as in residential buildings, business premises and industrial sites. It is also used in electronic circuits and systems that are susceptible to electric over-voltage situations, such as automotive systems, telecommunications and satellite systems. The SA20A-E3/73 is also suitable for controlling the inputs and outputs of electronic components, as it is able to provide protection in both directions.

Working Principle

The SA20A-E3/73 provides protection by diverting the excess voltage away from the electrical system in the event of a voltage surge or spike. The device works through a combination of resistive and capacitive technologies, to form an active clamp. The clamp works to maintain the voltage level within the specified limits, even in the case of a sudden voltage change. The voltage clamp then releases the diverted voltage, restoring the system to its original state.When using the SA20A-E3/73 it is important to note the type of voltage that it is capable of handling. The most common type being handled is the Sinusoidal Minimum Critical Voltage, which is the minimum voltage the device is able to withstand without causing damage. For this particular model the Sinusoidal Minimum Critical Voltage is 27V.

Installation Requirements

Before installing the SA20A-E3/73 it is important to ensure that the current flowing through the system is not more than the rated current of the device. It is also important to ensure that the electrical components that are being protected are compatible with the type of protection the device provides. When installing the device it is important to ensure that it is well ventilated and not subject to excessive heat. The installation should also be made in a manner that complies with local electrical regulations.

Conclusion

The SA20A-E3/73 is a type of TVS - Diode that is used to provide protection against voltage surges and electrical spikes. This device is most commonly used in power installations, electronic circuits and automotive systems, and works by forming an active clamp to divert the excess voltage away from the system. When using the device it is important to ensure that the current flowing through the system is not more than the rated current of the device, and that the installation is done in accordance with local electrical regulations.
