The B72214S2151K151 varistor has an operating voltage of between 5 and 1400 volts. It has a peak working pulse voltage of more than 1500 volts and a breakdown voltage of more than 900 volts. The device is thermally stable and has a maximum operating temperature of 125°C. It also has a maximum power dissipation of up to 5000 mW.

Working Principle

The B72214S2151K151 varistor works on a principle known as metal oxide varistor (MOV). This is basically a type of voltage-dependent resistor which is formed by using a metal oxide film on the surface of a ceramic or semiconductor material. The MOV varistor has two terminals that are connected in series and the voltage drop across it is proportional to the applied voltage. When the voltage is applied, the film experiences a change in its electrical resistivity, which enables it to control the amount of current flowing through it.

The B72214S2151K151 varistor works by clamping the peaks of the incoming voltage waves within its working limits, while allowing the troughs to pass through unaffected. As the incoming waveform exceeds its peak limit, the varistor increases its resistance in order to limit the current flowing through the system, thus protecting the sensitive components. The device also helps to protect the system from overvoltage and other transient voltage events.

The B72214S2151K151 is typically used in applications that require an increase in transient protection against potential voltage spikes. Its ability to provide protection against ac and dc transients makes it a very popular choice for many different types of industrial and consumer applications. It is also a popular choice for automotive applications such as protection against power line surges, lightning strikes, and short circuit situations.

The B72214S2151K151 varistor is a reliable and cost-effective solution for transient protection. It is available in a wide variety of shapes and sizes, making it a great choice for many different types of applications. Whether for commercial or industrial use, the B72214S2151K151 is an excellent choice for providing superior protection against transient voltage events.
