A Transient Voltage Suppressor (TVS), also known as a “transient voltage surge suppressor”, is an electrical component commonly used in electronic circuits to limit and protect electronic systems against transient overvoltage disturbances and electrical transients. The most common type of TVS component is the Varistor, a nonlinear resistor whose resistance decreases under an increasing voltage. The B72210S2551K501 is a type of Varistor that can be used to provide protection for different types of electronic products.

The B72210S2551K501 has a wide range of application fields for its Varistor characteristics. It can be used in a variety of electronic circuits in order to protect them from overvoltage events. It can be used in UPS systems, computer systems, power supply units, solar power systems, motor controllers, robotic applications, and many other industrial applications.

The working principle of the B72210S2551K501 is that it is a non–linear resistor that acts as a voltage-dependent surge suppressor. When the voltage applied to the Varistor exceeds its defined threshold voltage (for this component it is 25.5 V), the Varistor starts to conduct electricity due to its non-linear, decreasing resistance characteristics. This current conduction has the effect of limiting and/or suppressing any overvoltage condition.

The B72210S2551K501 has a maximum voltage of 722 V and a maximum leakage current of 1 A. The maximum peak surge current rating is 1 kA for a 10/1000µs surge pulse. The B72210S2551K501 is constructed from a metal oxide varistor (MOV) with a UL 94V-0 rating. This Varistor has an 18.5 dB insertion loss at 10 MHz and a 20 dB Return Loss at 100 MHz.

In summary, the B72210S2551K501 is an example of a Transient Voltage Suppressor (TVS) component, specifically a Varistor. It has a wide range of application fields and can be used to protect electronic systems against transient overvoltage disturbances and electrical transients. Its working principle is based on the non-linear, decreasing resistance characteristics of the Varistor, which starts to conduct electricity as soon as the applied voltage exceeds its defined threshold voltage. It has a maximum voltage rating of 722 V and a maximum peak current surge rating of 1 kA.
