B72240L0750K102 Datasheet/PDFTVSs, also known as transient voltage suppressors, MOV (Metal Oxide Varistors) and other varistors are common voltage protectitors. They are mainly used to protect electronic equipment from voltage changes and surge damage. Among them, the B72240L0750K102 application field and working principle is discussed in this article.
Application field
B72240L0750K102 is a radial-leaded varistor with metal oxide material. It has a wide range of applications, such as overcurrent and overvoltage protection in the fields of communication and information technology, consumer electronics, automotive engineering, and medical equipment. It can also be widely used in the security management of dooms, internet cafes, villas, etc, and is often used for EMI (Electro Magnetic Interference) suppression in high frequency signal lines.
Working principle
In general, the B72240L0750K102 works by clamping the voltage to a specific clamp voltage. The working principle of the varistor is based on a nonlinear resistance effect. When the current-voltage of the varistor appears, the resistance value changes nonlinearly with the change of the current. When the voltage is higher than the nominal level, the resistance is very small, so that the current in the circuit increases rapidly; however, when the voltage decreases below the nominal level, the resistance increases greatly, and the current in the circuit is reduced accordingly.
In addition, when it works, the junction of the varistor not only performs overvoltage protection and overcurrent protection, but also dissipates the energy of the pulse so as to protect the connected circuit. That is to say, when the voltage is higher than the nominal level, the energy is dissipated by conduction in order to reduce the energy of the pulse.
Conclusion
In conclusion, B72240L0750K102 can provide multi-function protection in many application fields. It is one of the most common and widely used products in the field of voltage protectitors. It is an ideal choice for protecting the circuit.
