A transient voltage suppression (TVS) diode is a form of voltage regulator that provides surge protection to connected devices against voltage spikes, which are generated by lightning strikes, short circuits, and electrostatic discharge (ESD). The V-I characteristics of a TVS diode are similar to those of a Zener diode but with a much faster response time, which allows it to absorb transient voltages very effectively. The SA75 is a type of unidirectional TVS diode that can protect circuits with Operating Voltages between 4.65V and 59.7V from high-speed transient over-voltage faults, such as electrostatic discharge (ESD), electrical transients and lightning surges.

TVS diodes are commonly used in a variety of applications, such as data communication, computer networking, telecom, automotive electronics, control system and consumer electronic devices. The SA75 is designed to provide protection against ESD, lightning-induced transients and other over-voltage events. It has a lower breakdown voltage than other TVS diodes and can be used for a wide range of applications. The SA75 provides an operating voltage range from 4.65V to 59.7V with low clamping voltage and fast response time. It is a RoHS-compliant, bidirectional TVS diode, which can provide protection to both the positive and negative sides of the power rail.

The SA75’s working principle is essentially based on the Zener effect. When an overvoltage is applied to the diode, the electric field at the junction of the diode increases, causing the electrons to be accelerated into the junction and resulting in a current flow. This current flow, or avalanche, continues until the avalanche voltage is reached. At this point, the junction begins to act as a Zener diode, generating an avalanche voltage. The path of electrons through the junction is then reversed, creating a voltage clamp at the Zener voltage.

The SA75 is ideal for use in automotive systems, as it can withstand surges up to 5kV. Its fast response time means it can provide protection in as little as 5ns. In addition, it has a wide operating voltage range, making it suitable for a variety of applications. Furthermore, its low clamping voltage allows it to safely protect connected devices from overvoltage without damaging them.

To conclude, the SA75 is one of the most popular types of TVS diodes due to its fast response time, low clamping voltage, and wide operating voltage range. It is widely used in a variety of applications, such as automotive systems, data communication, computer networking, telecom, automotive electronics, control systems and consumer electronics. It is able to provide an effective protection against ESD, electrical transients and lightning surges.
