TVS - Varistors, MOVs and Their Application Field and Working PrincipleVaristors and MOVs (Metal-Oxide Varistors) are widely used in industrial electronics as surge protection components. They can help to prevent electrical surges and malfunctions as well as offering low impedance paths to grounding. The B72210S0500K151 is a popular high voltage, cheap and reliable varistor used to protect sensitive electronics against overvoltage transients and ESD (electrostatic discharge). In this article, we will discuss its application field and working principle.First, let’s take a look at the application field of the B72210S0500K151. This varistor is designed to offer effective suppression of overvoltage transients and electrostatic discharges (ESD). It is suitable for protecting telecom circuits, consumer and automotive electronics, computer systems, medical equipment, and any other applications requiring excellent surge protection. The B72210S0500K151 can effectively limit the surging of transient surges, including lightning, heavy equipment startup, motor startup, and inductive over voltages. Thus, it can effectively protect against damage due to equipment malfunction, high-level energy surges, and severe variations in environmental conditions.Now, let’s discuss the working principle of the B72210S0500K151. This varistor is a non-linear, low impedance component which operates on the principle of a voltage-dependent resistor. When the applied voltage is below or equal to the rated voltage, the resistance of the varistor will be very high. However, when the applied voltage exceeds the rated voltage, the resistance of the varistor will decrease rapidly and the current flowing through it will increase. This will cause the varistor to act as a clamp, diverting the current away from the sensitive electronic circuit and protecting it from damage.The B72210S0500K151 is a great option for surge protection applications. It is low cost, reliable and offers a high level of protection for the electronic equipment. Furthermore, it has a wide range of operating temperature and is suitable for both commercial and industrial applications. Thus, it is a great choice for anyone looking to protect their sensitive electronic equipment against surge and overvoltages.
