SA120 Application Field and Working PrincipleSA120 is a breakthrough in TVS (transient voltage suppression) diode technology. This new technology is designed to provide fast and reliable protection in the shortest possible response time. It is capable of protecting a variety of sensitive electronic components from Voltages in excess of 150V transient spikes.SA120 uses a special technology to limit the over voltage transients. This technology is called "voltage surge clamping" and is based on the principle of reverse-biased diode. The diode is placed in the line such that the reverse voltage is applied across it to "clamp" the voltage. The diode will be reverse biased and will act as an open switch in response to the over voltage transient, thus limiting the maximum peak voltage.The peak voltage is clamped to a specific level which is set by the forward drop of the diode, which is typically around 0.7V for silicon diodes. This clamped voltage is typically much less than the over voltage transient that could have been experienced, thereby protecting the protected components.SA120 is also designed to protect against multiple transients and can be used in applications where high-frequency transients may be present. It is also capable of providing a low-voltage protection to sensitive components.SA120 is available in a convenient surface mount package. It is very easy to install and does not require any special tools or expertise. It also offers a wide range of ratings from 10V to 150V; suitable for both industrial and consumer applications.SA120 is also designed to be extremely reliable and robust. It has been designed to withstand multiple transient voltages and multiple applications. It also has a wide temperature range which makes it suitable for a variety of operating conditions.Overall, SA120 is an ideal solution for protecting sensitive electronic components from over voltage transients. It is easy to install and reliable, making it a popular choice for those looking for a robust and fast transient voltage protection solution.
