TVS - Varistors, MOVs are the two primary types of transient voltage protection devices used in the power industry today. They protect sensitive electrical circuits from high voltage transients caused by line surges, lightning strikes, and other disruptions to power. The TMOV34S181MP is a Metal-Oxide Varistor (MOV) designed specifically to provide surge protection for industrial and consumer applications. It features an open-circuit protection voltage of 4.5V and a clamping voltage of 8V.

The MOV is designed to protect circuits from spikes and surges that occur due to the operation of high current circuits. In this type of application, the MOV is connected across the power line in series and the voltage drop across it is used to limit the maximum voltage in the circuit. The MOV also functions as an energy storage device, absorbing and dissipating the voltages produced by the peak current flows. In addition, the MOV offers a high power-handling capacity and a low thermal impedance.

The TMOV34S181MP is typically used in applications such as personal computers, power supplies, and communication equipment. It provides protection from spikes and surges up to 8 volts. The TMOV34S181MP is also suitable for use in low-power DC circuits such as those found in consumer electronics applications. The MOV has an operating temperature range of -40°C to 120°C and has an impulse withstand voltage of 430V.(at 10/1000s)

The working principle of the TMOV34S181MP is based on the Zener effect. When the voltage across the MOV exceeds the breakdown voltage of the device, the electrons in the MOV jump from the N-type material to the P-type material, releasing energy and forming an avalanche. This creates a low impedance path for current flow, diverting the surge or spike away from the protected circuit. The MOV\'s avalanche characteristics and the ability to handle high power levels make it a popular choice for use in surge protection applications.

The TMOV34S181MP is a cost-effective solution for protecting sensitive equipment from electrical transients. It offers a high power-handling capacity and a low thermal impedance, and is suitable for use in both industrial and consumer applications. It is important to note that the MOV can only protect circuits from transient voltage events, and should not be used as a substitute for fuses or other over-current protection devices.
