Transient voltage suppressors (TVS) are devices that protect electronic circuits against voltage spikes. Varistors, metal-oxide varistors (MOVs), and silicon avalanche diodes (SADs) are all types of TVS devices. The TMOV14R175M is a MOV that is often used in applications as an active protection device against transient voltage and surge current. In this article, we’ll discuss the application field and working principle of the TMOV14R175M.

Application Field of the TMOV14R175M

The TMOV14R175M is a robust and reliable varistor that can withstand high voltages and surges, making it an ideal choice for a range of safety critical applications in the consumer, industrial, and automotive industries. It is designed for use in harsh environments, making it suitable for a variety of transient voltage applications.

This device can be used in a variety of applications such as automotive power supplies, computers, audio equipment, communication equipment, motor control systems, and industrial equipment. It helps to protect these devices from overvoltage or current transients that could otherwise damage them.

Working Principle of the TMOV14R175M

The TMOV14R175M is a Metal-Oxide Varistor (MOV) which works on the principle of voltage-dependent resistance. The device consists of a metal oxide layer sandwiched between two metal plates. When connected in series with the load line, it acts as a voltage-dependent resistor, reducing the flow of excessive current and limiting the voltage.

The device operates on the principle of nonlinear resistance. The resistance of the device is constant at low voltages, but begins to increase exponentially when the voltage exceeds its rated voltage. This increase in resistance limits the current passing through the device, thus preventing damage to the connected devices.

The TMOV14R175M has a wide operating voltage range of between 4 V and 1.75 kV, and is rated for a surge current of up to 400A. It is also equipped with an internal thermal protection device that slows the thermal response in case of prolonged overvoltage or surge conditions. This is especially important for applications that require reliable protection from large, short-term transient voltages.

Conclusion

The TMOV14R175M is a versatile and reliable transient voltage suppressor that can be used in a variety of applications to protect electronic devices from overvoltage and current transients. It operates on the principle of voltage-dependent resistance and has a wide operating voltage range and a high surge current rating. It also has an internal thermal protection device that prevents the thermal response in case of prolonged overvoltage or surge conditions. As such, it is an ideal choice for safety-critical applications in the automotive, consumer, and industrial industries.
