A TVS - Varistors / MOVs is a popular type of electronic component used in circuit design to protect other components in the circuit from electrical transients, surges and other harmful conditions. The B72207S0350K311 is a popular example of a TVS - Varistors / MOVs that is used in many applications ranging from portable electronics to industrial applications. This article will discuss the application field and working principle of the B72207S0350K311.

The B72207S0350K311 is an unidirectional, unipolar TVS - Varistors / MOVs with a voltage rating of 350V. It is a 1-element, automotive-grade, surface-mount device designed to provide surge protection for up to 5kA (8/20µs). It is a cost-effective, small-package solution for all types of automotive applications. The B72207S0350K311 is designed to protect the electronics from transients arising from extreme voltage and current conditions. Its small size and low profile makes it ideal for use in tight spaces. It is usually mounted directly onto the PCB and is rated to handle peak power dissipation up to 400W.

In terms of application fields, the B72207S0350K311 is used in automotive applications such as navigation systems, airbags, powertrain control systems, anti-lock braking systems, and many others. It is also used in consumer electronics such as computers, LED lighting, and home-appliance controls. It can be used in a wide variety of industrial applications, such as motor controls, power supplies, and industrial machinery control systems. In all of these applications, the B72207S0350K311 is used as a protective component to prevent damage to the other components in the circuit from transients and surges.

The working principle of the B72207S0350K311 is based on a principle called the “Voltage Regulation Effect”. This principle states that when there is an increase in voltage across the component, the current will decrease with respect to its pre-existing value. This phenomenon is crucial in preventing the overvoltage of components in the circuit. The functioning of the B72207S0350K311 can be divided into two stages - clamping stage and absorption stage. In the clamping stage, the surge current is clamped as the source-to-drain voltage exceeds the specified clamping voltage, i.e., the rated breakdown voltage of the device. The absorption stage begins when the clamping voltage is exceeded. During this stage, the device dissipates the energy of the surge and the voltage across the device is reduced to a safe level.

In conclusion, the B72207S0350K311 is a popular type of TVS - Varistors / MOVs used in many different applications. It is designed to protect other components in the circuit from transients and surges using the Voltage Regulation Effect. It is commonly used in automotive and consumer electronics as well as in industrial applications. The B72207S0350K311 is a cost-effective, small-package solution for all types of power protection requirements.
