Back in the mid-1800s, the German physicist Georg Simon Ohm was the first to discover electric resistance and the first to measure it. Little did he know that his discovery would eventually lead to the development of voltage suppressors, also known as Transient Voltage Suppressors (TVS).

TVS are electrical components that are designed to limit transient over-voltage caused by inductive or capacitive switching operations. They are widely used in a variety of applications, including in the automotive, industrial, military and medical industries. One specific type of TVS is the B72210S0621K351 Varistor. This particular device is specifically designed to protect electronic circuits against transient over-voltage, such as those generated by lightning and ESD electrostatic discharges.

The B72210S0621K351 Varistor is a non-linear voltage deviates with two simple connections: one for the input, and one for the output. Within its operating range, the device can carry an extremely high-current and withstand a variety of heavily inductive loads. In addition, the device offers superior, uncompromised protection with no false triggering and no leakage current.

When voltage is applied, the energy stored in the Varistor’s dielectric junction is released, creating a voltage-limiting effect. The amount of energy stored depends on the size of the dielectric barrier and the distance between the two terminals of the device. Basically, the larger and thicker the dielectric barrier, the greater the energy storage, and vice versa.

In normal, everyday operation, the B72210S0621K351 Varistor acts as a clamping device that blocks or reduces voltage impacts. The device responds to electrical pulses, controlling their peak voltage, allowing only those that do not exceed the device’s specified levels to pass through. This process helps to protect sensitive electronic components from possible damage.

The B72210S0621K351 Varistor is also a very reliable and cost-effective solution in a wide variety of applications, offering superior performance and protection. Some of the most common applications of the B72210S0621K351 Varistor include motor starters, thermal protectors, power corrosion protection circuits, and many other low-voltage applications.

In summary, the B72210S0621K351 Varistor is a versatile device that offers unrivaled levels of protection. It is a highly effective way of preventing damage to sensitive electronic components from voltage spikes, allowing them to continue to operate for longer periods of time. By regulating transient over-voltage, the B72210S0621K351 Varistor ensures the reliable operation of electronic components in a wide variety of applications.
