TMOV25SP115E is a transient voltage surge suppressor, commonly referred to as a Varistor, MOV, or TVS. This device offers surge protection from electrostatic discharges and is used in a wide variety of electrical applications. This article will discuss the application field and working principle of the TMOV25SP115E Varistor.

TMOV25SP115E Varistors are most commonly used in the power supply and telecoms industry, as well as in automotive and other applications. They are used to protect equipment from voltage spikes or surges, which can cause damage or malfunctions in sensitive electronic components. The TMOV25SP115E Varistor is designed to absorb and dissipate the energy from any voltage surge before it reaches and damages the equipment.

TMOV25SP115E Varistors are designed with a narrow varistor voltage range and low peak current. This helps to ensure that the Varistor does not absorb or reduce the desired system levels of voltages. The device is also designed with low leakage current for low dissipation and low capacitance for high frequency applications. In addition, the TMOV25SP115E is UL certified, meaning it meets certain safety requirements and can be safely used in most applications.

The working principle of a TMOV25SP115E Varistor is fairly simple yet highly effective. It consists of a metallic oxide material that is formed into a round disc and placed in a ceramic housing. When in operation, if the voltage applied to the device exceeds its designed varistor voltage, the oxide material will become more conductive. This allows more current to pass through the Varistor, resulting in the absorption and dissipation of the excess energy. This process occurs rapidly, usually within a microsecond or two, to protect the connected systems from the voltage surge.

The TMOV25SP115E Varistor is designed to protect sensitive electronic components and equipment from transient voltage surges. They are well-suited for use in the power supply and telecoms industry, as well as automotive and other applications. The Varistor is designed with a narrow voltage range, low peak current, low leakage current, and low capacitance for high frequency applications. The Varistor is capable of rapidly absorbing and dissipating voltage surges through the injection of additional current to protect the circuitry from damage.
