B72542V1300K062

B72542V1300K062 are varistors, referred to as surge protective devices (SPDs). Varistors are an important device in overvoltage protection circuits and are designed to provide protection against voltage transients such as electrical surges. They are commonly used in applications where electrostatic discharge (ESD) protection is necessary and where circuit isolation is not required.

B72542V1300K062 are intended for protection against overvoltage transients resulting from lightning and other voltage surges. The device is constructed of a silicon nitride layer with a zinc oxide varistor ceramic body, which has a non-linear voltage/current characteristics. It can provide protection from both single-low and multi-level transients. B72542V1300K062 have a very low series inductance (less than 1Ω), which makes them suitable for high frequency applications.

The working principle of B72542V1300K062 is based on the non-linear characteristics of the ceramic body. The device acts as a voltage-dependent resistor with a high resistance at lower voltages and a lower resistance at higher voltages. When an overvoltage transient is applied, the resistance of the device decreases allowing the current to flow through the circuit. This reduces the voltage to a safe level and protects the circuit from damage.

B72542V1300K062 are widely used in various applications, such as telecommunications, medical equipment, consumer electronics, industrial equipment, automobiles, and more. In telecommunications, they protect communication lines from lightning and power surges. In medical equipment, they protect medical equipment from EMI and power surges. In consumer electronics, they protect appliances such as TV, DVD players, computer, etc. from ESD, as well as from voltage and current surges, while in automobiles, they protect the electrical systems from transient overvoltages.

B72542V1300K062 are also used in telephone and data protection systems, such as in telephone switching systems, power line communication systems, cable television systems, and modems. They are used to provide protection from transient overvoltages and from high temperature and humidity that can damage the sensitive components of these systems.

In summary, B72542V1300K062 are varistors that provide overvoltage protection for circuits from single-low and multi-level transients. They are constructed with a non-linear, high-impedance silicon nitride layer and a zinc oxide varistor ceramic body. They are widely used in various applications due to their low series inductance, large surge capacity, high-frequency response, and low leakage current.
