B72220S2211K101

The B72220S2211K101 is a product of the TVS - Varistors, MOVs (Transient Voltage Suppressors, Metal Oxide Varistors) class of components used for protecting against voltage transients. It is a unidirectional type which is rated for 10A and 800W peak pulse power. It allows a wide operating temperature range from -55C up to 150C and has a clamping voltage rating of 39V.

TVS - Varistors, MOVs are components designed to protect sensitive circuits from transient voltages. They are often referred to as "transient voltage suppressors" since they absorb and dissipate surges of energy caused by voltage transients. These varistors are available with two basic configurations, uni-directional and bi-directional. The uni-directional type absorbs voltage of one polarity only, clamping it to a specific voltage. On the other hand, bi-directional varieties are able to absorb voltage from both polarities.

The working principle of TVS - Varistors, MOVs is based on an electro-mechanical mechanism. When a surge of current with a certain polarity passes through the component, a mass of metal oxide particles is moved against a spring, creating a contact with two electrodes. This creates a clamping effect, which offers a short low resistance path for the surge to be diverted through. The strength of the clamping effect is based on the size of the mass, the type of metal present and the stiffness of the spring. The size of the mass determines the maximum rate of change of voltage that the component can absorb before the metal oxide starts to move.

The B72220S2211K101 can be used in many different applications, from circuit boards and telecom lines, to power supplies and communication systems. It can be used in automotive electronics, consumer electronics, industrial systems, and computer systems for protection against voltage transients. It is also suitable for EMI/EMC protection, due to its high absorption rate and low leakage current.

Overall, the B72220S2211K101 is an ideal solution for protecting sensitive circuits from transient voltages and ensuring EMI/EMC protection. It is able to clamp the voltage to a specific voltage rating and offer excellent thermal stability and high absorption rate, making it suitable for various applications.
