Application Field and Working Principle of B72660M0111K072

TVS (Transient Voltage Suppressor) devices, also known as varistors, MOVs (Metal-Oxide Varistors) and surge arresters, are used to protect high-voltage circuits from voltage transients generated by SA/ESD (Surge Arrester Electromagnetic Discharge/Electrostatic Discharge) or EMC (Electromagnetic Compatibility) interference. B72660M0111K072 TVS is a high-performance device with a maximum clamping voltage of 2500 V. It can withstand peak currents up to 10A, and is ideal for protecting sensitive electronic components from over-voltage transients.

B72660M0111K072 offers 250V of breakdown voltage in a SOD123 package with an extended power dissipation rating of 250V, making it suitable for use in a variety of applications, including automotive, industrial and consumer. As a general-purpose surge protection device, it has a wide range of applications in automotive, motorsport, electromechanical, energy systems and consumer electronics regulated markets. It can also be used in unprotected circuits to provide voltage protection.

Working Principle of B72660M0111K072

The operation of B72660M0111K072 is based on the fact that the current is proportional to the voltage applied across the device, thus providing protection from overvoltage transients. When exposed to high-voltage transients, such as an electrical surge, the device absorbs the energy of the transient, limiting the peak voltage that can pass through it and thus protecting the sensitive electronic components. As the device absorbs more energy, its current increases and its resistance decreases, allowing it to absorb more energy.

The circuit protection provided by B72660M0111K072 depends on its energy-dissipating characteristics. As the MOVs safely divert excess current away from the circuit, they prevent voltage transients from damaging sensitive components and help ensure the circuit’s long-term stability. It also provides protection from ESD or EMI-induced transients.

Conclusion

The B72660M0111K072 is a versatile TVS device with a wide range of uses in different industries. With its high breakdown voltage of 250V, peak current rating of 10A, and low power dissipation, the device provides superior protection against voltage transients and ESD or EMI interference. Its operation is based on the fact that the current is proportional to the voltage applied across the device, allowing it to absorb energy from high-voltage transients and protect sensitive electronic components from overvoltage transients. The device is therefore ideal for a range of applications that require protection from voltage transients or ESD.
