TVS - Varistors, MOVs (Metal Oxide Varistors or Transient Voltage Suppressors) are components that are designed to protect circuits from voltage transients (also called spikes or surges) and are commonly found in electronic devices such as TVs, computers, and even automotive electronics. The V47ZS3 is an example of such a device, and its application field and working principle can be outlined as follows.

The V47ZS3 is designed to protect equipment from transients arising from surges in the supply, either as a result of lightning strikes or switching of nearby equipment. The device is rated for a working voltage of 270 volts, with an equivalent series resistance of 7.5 ohms, and a susceptibility of <50 ohms under normal operation. When the electrical load on the device is exceeded, the device rapidly changes from its low resistance state to a high resistance state, dissipating the resulting energy as heat.

The device is constructed from a zinc oxide ceramic disc, which acts as the resistor. The disc is covered with an insulating coating on one side and is fitted with two insulated metal electrodes. The electrodes are then connected to the circuit protected by the V47ZS3. When the device is triggered, a spark is created across its terminals, changing the resistance of the circuit from a low to a high level.

The V47ZS3 is designed to work as part of a larger system. It must be used in combination with other components such as fuses, TVS diodes, and circuit breakers in order to provide effective protection from potential transients. It must also be chosen with care to ensure compatibility with the other components in the system.

One of the main advantages of the V47ZS3 is its small size, which makes it suitable for use in space-constrained applications. It is also relatively inexpensive compared to other surge protection devices. Additionally, the device can be used in a wide range of applications, from industrial machinery to consumer electronics – all of which require reliable and efficient protection.

In short, the V47ZS3 is a reliable transmitter voltage suppressor (TVS) with a working voltage of 270 volts and an equivalent series resistance of 7.5 ohms. The device works by rapidly changing from a low resistance state to a high resistance state when the electrical load on it is exceeded, dissipating resulting energy as heat. The device is small, inexpensive, and reliable, making it suitable for a wide range of applications.
