MOV-14D751K application field and working principle

TVS (Transient Voltage Suppressor) Varistors (or transient voltage surge suppressors) are an important component in electrical and electronic circuits. In order to protect devices from electrical surge, these varistors are placed in circuits which act as a voltage limiting device. MOV-14D751K is a popular type of TVS varistor, which withstands high voltages and has high surge current ratings. It is typically used in power supplies, audio amplifiers, communication systems, robotics, security systems, and many other applications where voltage surges need to be managed.

The MOV-14D7512K is a silicon carbide based varistor with a round metal oxide disk. It consists of a ceramic body, with a brass or bronze outer casing and an internal electrode. In its simplest form, the device acts as a resistor when a steady-state voltage is applied to it. When a high-voltage transient is applied, the varistor becomes conductive, allowing the charge to be diverted away from the protected component and preventing it from being damaged in the process. Additionally, due to its material properties, the chip also acts as a low-pass filter, further reducing the amount of high-frequency noise present in the circuit.

The MOV-14D751K is one of the highest voltage ratings that can be found in the market. It is capable of handling strong voltage present in all AC power applications. When a transient wave is applied to the device, the metal oxide disk within the varistor breaks down and absorbs the energy from the surge. This breakdown generates a surface leakage current due to the low density gas release during the deterioration process.

The MOV-14D751K can provide a wide range of surge current absorption capabilities, from thousands of amps for brief microseconds to tens of milliamps for longer periods of time. Since this voltage-dependent resistor has a non-linear resistance response, it has the capacity to dissipate large amounts of energy safely. The MOV-14D751K also acts as a lightning arrestor, protecting the system from very powerful electric discharges.

In addition to its lightning protection qualities, the MOV-14D751K is a relatively cost-effective solution for protecting against electrical overvoltage and overcurrent events. It also offers high heat dissipation capability and reliable operation even under extreme conditions. The device is also simple to install and comes in the standard profile form.

The MOV-14D751K is a versatile and cost effective solution for protecting against electrical overvoltage and overcurrent events. It is a highly reliable and widely used type of TVS Varistor, suitable for many power supply, audio amplifier, communication systems, security systems, robotics, and lightning protection applications. With its non-linear resistance response and robust capabilities, the MOV-14D751K can provide long-term protection against dangerous voltage surges.
