TVS - Varistors, MOVs

TVS (transient voltage suppressors) are electronic components that are used to protect a circuit from transient voltages, also known as voltage surges or spikes and electrical overstress (EOS). These electronic components are typically used in automotive systems, power supplies, battery management systems, and other applications where high voltage protection is needed. Varistors and MOVs (Metal Oxide Varistors) are two common types of TVS that are used to provide protection against transients.The B72207S0251K211 is a varistor device that is designed specifically for use in automotive applications. It is designed to protect automotive electronics and wiring from transient voltages caused by voltage surges or electrical overstress. The B72207S0251K211 has a capacitance value of 251 pF, which makes it suitable for use in high current applications. It has a breakdown voltage of 18-19.5 VDC and a maximum peak pulse current of 4 kA.The working principle of the B72207S0251K211 varistor is based on the properties of a varistor. A varistor is a non-linear, frequency dependent resistor that provides protection against voltage transients. It works by clamping the voltage to a safe level when a surge of current occurs. The varistor has two important characteristics that make it ideal for use in automotive applications: First, it has a low capacitance, which means it does not significantly affect the system\'s response time. Second, it has a high breakdown voltage, which gives it a large margin of safety against transients.The B72207S0251K211 varistor is typically used in automotive systems to protect against voltage transients and EOS events. It can also be used in power supplies, battery management systems, and other applications where high voltage protection is needed. The device provides excellent protection against voltage transients and EOS events, allowing it to be used in a variety of different automotive applications.In conclusion, the B72207S0251K211 varistor is an excellent choice for use in automotive systems, power supplies, and other applications where high voltage protection is needed. It has a low capacitance value, which makes it suitable for use in high current applications, and a high breakdown voltage that provides a large margin of safety against transients. The device is also designed to provide optimal protection against voltage transients and EOS events, making it an excellent choice for use in automotive applications.
