TVS (Transient Voltage Suppressors) is a type of resistor that is used to limit the surge or transient voltages, which can cause damages to the system. Varistors, MOVs (Metal Oxide Varistors) and Protection Diodes are some of the important components in this category. Varistors, MOVs and Protection Diodes are mainly used to protect the system from surges and over voltage transients.

VK104MK151R025P050 is a specific type of varistor designed to provide surge and transient protection in power supply. It is a Metal Oxide Varistor and generally used as transient voltage suppression diode. It is a voltage-dependent component that can protect up to 25 volts. It is a 150vac, 2 pole varistor with a peak clamping voltage of 50 volts.

The working principle of VK104MK151R025P050 is to act as a low resistance path when large transient voltage and surge occurs. When a voltage suddenly increases due to a transient event, the MOV starts to conduct current. With the activation of the MOV, the voltage is clamped to the threshold voltage. For this MOV, the threshold voltage is about 50 volts. Thus when a transient voltage above 50 volts occurs in any of the two direction, the MOV will start to conduct and reduces the voltage to avoid any further damages.

This type of varistor can be used in various automation systems, electronic circuits and power supplies. Examples of applications are DC/DC power supplies, motor controls, instrumentation systems etc. It can be used in both AC and DC circuits.

VK104MK151R025P050 provides voltage protection and surge protection. It helps protect sensitive equipment from transient voltage and steady surges that can cause a device to malfunction or fail. The transient voltage protection is provided for the common Mode that is the voltage between two terminals. The protection is given for both positive and negative going surge and transients on both terminals.

In conclusion, VK104MK151R025P050 is a Metal Oxide Surge Suppressor varistor with a 150VAC voltage range and a peak clamping voltage of 50V. It is used to offer some degree of protection from transients and surges in a power supply. It works by providing a low-resistance path for transient voltages and current, thus protecting the system from further damages. The applications of this MOV are mostly found in automation systems, electronic circuits and power supplies.
