TVS (Transient Voltage Suppressors) - Varistors, MOVs, are among the most widely used components in a variety of electronic systems. They are designed to protect sensitive devices from extreme conditions by helping to protect them from the effects of overcurrent, overvoltage, and surge transients. The MOV-14D911K is a TVS Varistor that is specifically designed to protect against overvoltage and surges.

The MOV-14D911K is an unidirectional TVS that is based on silicon-oxide-nitride-oxide-silicon (SONOS) technology. The devices feature a high surge current rating of 1,000A (10/1000μs) and capability of handling transient surge voltages of up to 14V. The MOV-14D911K has an ESD (Electrostatic Discharge) protection of 12kV; it also boasts a low turn-on voltage of 4.2V and a leakage current of 0.15mA. All these features make it ideal for sensitive electronics.

MOV-14D911K is mainly used in automotive, industrial, computer, telecommunications, consumer electronics, and other applications. It can be used to protect circuit boards, allowing them to survive the voltage or power surges that may occur. It is typically used in automotive electronics to protect sensitive components from overvoltage or surge conditions that may occur due to lightning or power line faults. It is also used in consumer electronics, providing protection against power surges caused by short circuits or other faults in the power supply.

The MOV-14D911K works by limiting any single pulse current below a certain level. This limitation occurs due to the increased resistance of the MOV-14D911K when an excessive voltage is applied. The components\' impedance increases as the voltage applied increases, and the current polarity is unidirectional, which helps protect the device from power surges and overvoltage. As the current tries to exceed the unidirectional limit, the MOV-14D911K will begin to increase in resistance, thus blocking the excess current.

The MOV-14D911K also features an SOA (Safe Operating Area) that helps protect the device from overcurrents, such as those caused by short-circuits. An SOA is used to limit the energy that the TVS can draw from the power source in the event that it is exposed to high currents. This feature helps protect the components from being damaged due to excessive heat generated by the absorbed current.

In addition to these features, the MOV-14D911K also features a low internal capacitance of 1 pF. This helps reduce noise interference, making the device better-suited for high-frequency applications. The low-leakage current also helps reduce power consumption, allowing for more efficient operation.

The MOV-14D911K is a versatile and reliable component, and its unique features make it ideal for a variety of applications. Its ability to effectively protect circuits from power surges, overvoltage, and overcurrent, makes it a great choice for protecting sensitive electronics.
