TVS - Varistors, MOVs

The B72225T4171K101 is a Transient Voltage Suppressor (TVS) Diode, from the Varistor family of products, manufactured by EPCOS. Varistors are semi-conductors designed to provide protection from transient voltage spikes caused by Electro-Static Discharge (ESD) and other electromagnetic interference (EMI).The B72225T4171K101 is a two-lead component, with a lead spacing of 4 mm and a body size of 5.6 x 4.7mm. It can be installed on PCBs or wire-wrapped on a bare-copper-wire board. The device is also RoHS compliant, and its operating temperature range is -40°C to 125°C.The B72225T4171K101 has a working voltage of 17V, and its peak pulse power at 10/1000μs (8/20μs) is 1750W (650W). Its ESD protection level is 15kV, and it is rated to handle an EMI voltage level of 400V. With its wide operating temperature range and high rated values, the B72225T4171K101 is suitable for use in a variety of applications, including telecommunications, consumer electronics, automotive, industrial controls, and computer/peripheral equipment.The working principle of Varistors relies on the materials used in their construction. The most commonly used materials are zinc oxide and metal oxide. In a Varistor, these materials form a matrix structure with an electrode layer. The material in this matrix has a crystal-like structure that is composed of bi-stable particles. When an AC or DC voltage is applied to the electrodes of the Varistor, a polarization current starts flowing through the matrix. This current depends on the type of material used, and due to the bi-stable particles, the current will cause a semi-conducting varied-resistance path to be formed in the Varistor. As a result, the Varistor can regulate and protect the circuit from both AC and DC electric surge, as well as from ESD.In addition, the surge protection provided by Varistors can be enhanced by adding a heat sink to the component. A Varistor with a heat sink can efficiently dissipate the energy generated by the voltage spike. The heat sink and Varistor work together to reduce or eliminate the additional stress placed on the circuit by the surge.In conclusion, the B72225T4171K101 is a high-end Transient Voltage Suppressor designed to provide reliable protection against ESD and other transient voltage spikes. Its wide temperature range and high rated values make it suitable for a number of electronic applications. The device’s working principle is based on the materials used in its construction, which form a semi-conducting varied-resistance matrix. To further enhance the surge protection provided by the B72225T4171K101, a heat sink can be installed.
