MOV-14D330KTR Circuit Protection

TVS - Varistors, MOVs is one of the most widely used protective device in circuit design. This article will discuss the application fields and working principles of MOV-14D330KTR.

What are MOV-14D330KTR?

MOV-14D330KTR is a silicon avalanche voltage suppressor which is offered within the MOV-14D Series. It is a 14-pin surface mount diode, ChipFET, with 1-pair of series connected and epoxy- encapsulated 400V/330V protection thyristors. MOV-14D330KTR has a 150mA DC hold current and provides excellent protection against electrostatic discharges.

Application Fields of MOV-14D330KTR

MOV-14D330KTR has a wide range of applications including the protection of computer interfaces, automotive controls, telecom equipment, line transients, industrial control/computer systems, ESD protection, and power supplies and always serves as a protector of overvoltage and overcurrent circumstance. Because MOV-14D330KTR is provided with many advantages, such as high surge capability, low power consumption, and fast response times, these devices are capable of withstanding up to 3000 V. Thus, MOV-14D330KTR is well suited for use in automotive control systems, computer interfaces, telecom equipment, and power supplies.

Working Principles of MOV-14D330KTR

MOV-14D330KTR begins to conduct current when the incoming voltage reaches the rated voltage of the device. Generally, it will absorb the excess pulses and reduce the current to a safe level. Under normal operating conditions, the resistance of MOV-14D330KTR is very low and it has the ability to suppress up to 400 volts of static operating voltage.

After the initial surge, the current keeps on flowing through the MOV-14D330KTR element. As a result, the MOV-14D330KTR absorbs the excess electrical pulses and brings down the current to a safe level. Its resistance during this period is very low which allows the MOV-14D330KTR to suppress up to 400 volts. This way, MOV-14D330KTR acts as a protector and protects the circuit from overvoltage and overcurrent.

MOV-14D330KTR also provides excellent transient protection from surges such as those that occur during power outages. It protects the circuit by limiting the voltage and current spike that may occur during the power surge. This helps to prevent damage to the circuit components and reduce downtime caused by power outages.

In summary, MOV-14D330KTR offers great protection against overvoltage, overcurrent, and transient voltage spikes. It is widely used in many applications due to its low-power consumption, fast response times and high surge capability. It is an ideal device for automotive, telecom and power supplies applications.
