TVS - Varistors, MOVs

The B72220T0102K105 is one of the most common types of varistors, which serve as a form of surge protection commonly used in electrical and electronic applications. They are also known as “transient voltage suppressors” and are designed to protect circuits from excessive voltages. The B72220T0102K105 is a non-linear, two-terminal, radial leaded, MOV device with a rated Maximum Continuous Operating Voltage (MCOV) of 21.3V.

Applications of the B72220T0102K105

The B72220T0102K105 is suitable for a broad range of applications, including consumer electronics, data communication systems, motor control and power supplies. It is typically used in devices with high exposure to transient voltage surges, such as laptops, personal computers, and other consumer electronic devices. It protects these devices from voltage spikes, which can cause damage to connected components. The B72220T0102K105 is also used to protect a variety of industrial applications, such as automotive systems, telecommunications, and lighting.

Working Principle of the B72220T0102K105

The working principle of the B72220T0102K105 is straightforward. When a voltage spike exceeds the normal operating voltage of the circuit, the B72220T0102K105 instantly reacts and dissipates the extra voltage by “clamping” it to a lower voltage level. This voltage level is called the Maximum Clamping Voltage (MCV) and is typically a few volts lower than the normal operating voltage. This in turn protects the connected device from damage due to excessive voltage levels.

The B72220T0102K105 varistor is also known for its excellent surge response time, which is typically around 1 nano-second. This fast response time makes the B72220T0102K105 an ideal choice for applications where surge protection must be provided quickly. Additionally, the B72220T0102K105 has a long life expectancy and can withstand multiple transient voltage spikes over its lifespan without sacrificing performance.

In summary, the B72220T0102K105 varistor is a two-terminal, non-linear, MOV device that offers efficient and reliable surge protection for a wide range of applications. It quickly responds to voltage spikes to protect connected components from damage and has a long life expectancy, making it an ideal choice for many applications.
