A varistor, TVS or MOV (Metal Oxide Varistor) is an electronic component that can absorb, or clamp, the power of an electrical voltage for a certain amount of time. This clamping activity is then used to protect circuits and components from voltage fluctuation and power surges, as it is designed to resist the sudden increase and decrease of voltages to protect the surrounding circuitry. The V47ZA20PX1347 is a particular metal-oxide varistor, also known as an MOV, that has a number of properties and uses.

The V47ZA20PX1347 MOV has a voltage rating of 3.8 Volts, a rated current of 2.15 Volts, a discharge current of 2000A at 10/1000 ms and a power rating of 6 Watts. It also has an operating temperature range of -5 to 85°C and features a small size of 7.5mm x 5.5mm x 4mm, making it ideal for use in space-constrained applications. In addition, this varistor has a response time of 1ms and a capacitance at 1 kHz of 120pF. These features make it well-suited for a variety of protective applications.

The V47ZA20PX1347 varistor is used in a variety of applications, including automotive, telecoms, medical, telecommunications, industrial control and consumer electronics. It is well-suited for protecting electronic devices from electrostatic discharge (ESD), over-voltage, inductive load switching, and lightening surges. Additionally, it can be used as protection against electrical shock due to its response time and ability to absorb power. In areas where high power and high voltage spikes are present, the V47ZA20PX1347 is especially helpful in protecting sensitive electronic components and other circuitry.

The working principle of the V47ZA20PX1347 MOV is the same as that of a resistor: when an over-voltage surge occurs, the MOV’s resistance increases, allowing it to absorb more power than a regular resistor could, thereby dissipating the energy of the surge. As a result of this protection, the capacitance at the MOV increases to prevent any further overvoltage spikes. This is done by canceling out the over-voltage spike, thereby protecting the surrounding circuitry. The V47ZA20PX1347 MOV is also equipped with an internal thermal fuse, which is triggered if the MOV’s temperature becomes too high and shuts off the circuit to prevent any further damage.

In conclusion, the V47ZA20PX1347 is a metal-oxide varistor that is well-suited for a wide variety of applications where over-voltage, ESD, and other electrical hazard protection is needed. It has a number of features, such as a power rating of 6 watts, a response time of 1ms, and a capacitance at 1 kHz of 120pF, which makes it ideal for protecting sensitive circuitry. Additionally, its working principle involves a thermal fuse and the absorption of power when voltage surges occur, allowing it to protect the surrounding circuitry from overvoltage spikes.
