B72220T2461K105

TVS diodes, also called transil diodes, are components specially designed to protect against various voltage transients (also called surges) in suspension, power and data lines - be it ground, AC or DC power sources. The B72220T2461K105 is one such TVS diode, also part of a special family of thermally protected components called Varistors, MOVs (metal oxide varistors).

Varistors, MOVs are voltage-dependent resistors that are used to reduce the effects of transients and surges in power and other lines. MOVs are usually made of zinc oxide that is compressed into a disk or into two disks. This structure gives MOVs the ability to absorb surges and transient voltages. MOVs are able to effectively discharge any transient voltage that surpasses the rated voltage of the MOV. This particular property is very important, as it allows MOVs to keep the voltage within a safe range, eliminating the possibility of a catastrophic failure as it would happen if a conventional fuse or surge suppressor would be used.

B72220T2461K105 is an encapsulated MOV component with an epoxy coating and several additional features, such as a thermistor, for surrounding components protection from overheating. This component is the ideal solution for a wide range of industrial applications, including UPS systems, AC and DC motors, welding equipment, and other high-power, voltage-sensitive applications. Original B72220T2461K105 components are available with various working voltage ratings and different power ratings from 3A up to 50A.

The B72220T2461K105 TVS diode has a bi-directional symmetrical design, meaning that it is ‘polarity-insensitive’, meaning it can withstand transients from either polarity, allowing it to be installed in any position with respect to the power source. It has a nominal discharge current of 10kA (8/20 μs waveform). The diode has an Insulation Distance (impulse spark plug) of 10kV, which can also be used to help protect components against high-frequency audio/video noise.

The B72220T2461K105 is also equipped with a separate thermistor feature. This feature works in conjunction with the diode to provide an additional layer of protection to other components. The thermistor is designed to rapidly react to an increase in temperature above the normal working temperature of the diode. When this happens, the thermistor kicks in and gradually begins to lower the current passing through the diode, helping to reduce the risk of a power source failure.

In summary, the B72220T2461K105 TVS diode is a versatile component designed to protect AC and DC power sources, as well as any other sensitive components that are connected to it. It offers a range of advantages over traditional protection components such as fuses and surge suppressors. It is a must-have in any situation where a power source needs to be protected from voltage transients and surges.
