B72500E0250K060 Circuit Protection

TVS - Varistors, MOVs are dynamic components that can be used for protection such as overvoltage or overcurrent protection, and are used in a wide range of applications. B72500E0250K060 is a specific type of TVS - Varistors, MOVs, which have distinct application fields and working principles.

Application Field

B72500E0250K060 is a TVS - Varistors, MOVs used in power supply, signal and communication circuits, such as PC motherboard, server, network adapter, LCD power supply, industrial control automation, security monitor, etc. It is designed to prevent or limit the transient voltage or surge current caused by the switch-on or short-circuiting of the external power transistor or other components, thus protecting the power supply circuit and various electronic components against damage.

Working Principle

B72500E0250K060 is a ceramic, avalanche-proof overvoltage protection device which is composed of special metal oxide ceramics and zinc oxide ceramics. Its voltage is modulated by changing the thickness or diameter of the chip. The varistor\'s voltage is determined by its construction parameters, such as materials, thickness, contact area and other factors.The working principle of the B72500E0250K060 Varistor is that when a voltage exceeding the rated voltage is applied to the Varistor, its resistance decreases and a corresponding current flows, thus preventing or limiting the overvoltage. Furthermore, when the instantaneous electrical overvoltage reaches a certain critical value, the preloaded voltage of the chip is exceeded, large-current avalanche conduction occurs inside the chip, and the voltage on both sides of the chip returns to a normal level. This is the function of a transient voltage suppressor diode.

Conclusion

The B72500E0250K060 Varistor is a type of TVS - Varistors, MOVs, and is widely used in power supply, signal and communication circuits for overvoltage or overcurrent protection. It can effectively prevent short-circuits and an excessive voltage, protecting the power supply circuit and various electronic components from potential damage. Moreover, the working principle is based on changing the chip\'s resistance and the consequent current when the voltage exceeds the rated voltage.
