Surge protective devices such as TVS - Varistors, MOVs are important components in electrical systems that provide protection from electrical surges and transients. The B72225S4271K101 is a Metal Oxide Varistor (MOV) that is used for over-voltage protection of electrical circuits and equipment from surge and transients.

A Metal Oxide Varistor (MOV) is a voltage-dependent, non-linear resistor with a much higher resistance which is lower than that of a linear varistor when an over-current or high-voltage surge is experienced. The B72225S4271K101 is a non-linear resistor with an operating voltage range of 18 to 33V and a maximum peak pulse current of 4.75KA. It is designed to be highly effective in absorbing large surge currents without causing permanent damage to the device or circuit components.

The B72225S4271K101 is a segmented, two-terminal device that functions as a voltage limiter or surge suppressor. It is typically used in AC line protection for home and commercial appliance. It is also used for over-voltage protection of electronic systems such as automotive electronics,telecommunications, computing, and industrial control systems. When an over-voltage or surge is experienced, the device quickly limits the excessive voltage and current to a safe level, thereby providing protection to the interconnected circuit components from such electrical surges.

The working principle of the B72225S4271K101 is simple: when the voltage across the terminals of the device increases above a certain limit, a large amount of current will flow through it which effectively "clamps" the voltage at the terminals to the clamping voltage of the device. This clamping action helps protect the circuit, components, and devices from excessive surges in voltage and current.

The B72225S4271K101 has a good pulse handling capability and can survive multiple surges without any damage. Its robust design also ensures long-term durability and reliability in operation. In addition, the device is also RoHS compliant and has a lead-free construction for environmental safety.

In conclusion, the B72225S4271K101 is a versatile surge suppression device that is suitable for a wide range of applications. Its robust construction and high surge-handling capability provide reliable performance and protection in electrical systems. Furthermore, it is RoHS compliant, making it an eco-friendly option for over-voltage protection.
