Transient Voltage Suppressors (TVS) have been used in a wide range of industrial and commercial applications for more than four decades to protect electronic systems from electrical failures or high surge voltage, and have since become increasingly common.

TVS come in various forms, with the most popular being the avalanche-based diode, which is intended to protect digital circuits from overvoltages and is also referred to as a Zener diode. Mixed technology TVS are a more recent development, and offer significantly more protection than traditional diode-based TVS.

Mixed technology TVS provide protection for both digital and analog circuits, along with the ability to detect and reduce interference. This is achieved using a combination of high-voltage diodes and transistors in order to reduce the amount of voltage applied to the protected circuits. They are designed to produce a steady current to protect the circuit from any external voltage spikes, while at the same time limiting the current flow.

The key features of mixed technology TVS are that they are designed to provide improved ESD protection, as well as improved RF interference protection. These features are provided by two levels of protection; one is the ESD protection, which is accomplished by using the high-voltage diodes and transistors to dissipate any voltage that may present itself above the normal operating voltage of the device. The second level of protection is the RF interference protection, which works by using the same diodes and transistors to reduce or eliminate the amount of RF interference.

The working principle of a mixed technology TVS is relatively simple. When an external voltage spike is detected, the TVS is triggered and the amount of current that flows is limited. As the voltage declines, the current flow is restored to its original level. This process of limiting current flow helps to maintain the stability of the device, which helps to extend its life and reduce potential damage caused by a sudden increase in voltage.

Mixed technology TVS are most commonly used in a variety of consumer electronics, ranging from laptops and cell phones to digital cameras and video game systems. The primary purpose of these devices is to provide improved ESD protection, as well as protection from RF interference. They are also found in industrial applications, including motor control systems, power supplies, and other similar applications.

Mixed technology TVS provide the user with increased protection and reliability, as well as improved performance, which can help to extend the life of the system or device. They are also cost-effective, as they are relatively inexpensive and easy to install.

In conclusion, mixed technology TVS offer a number of advantages when compared to traditional diode-based TVS, and are increasingly being used in a wide range of applications. They provide improved ESD protection, as well as improved RF interference protection, as well as the ability to detect and reduce interference. They are relatively inexpensive and easy to install, making them an attractive option for consumers and businesses alike.
