What is the role of TVS diode in the protection board?

The application of TVS diodes in protection boards is also reflected in their reusable characteristics. Due to its fast response and high power tolerance, TVS diodes can respond multiple times in a short period of time

The overvoltage problem in the circuit will not fail due to a single overvoltage. This reusable feature makes TVS diodes a long-term reliable protection solution.

The primary task of TVS diodes in the protection board is to prevent damage to the circuit from overvoltage. In practical applications, the voltage of the power supply may suddenly rise, or overvoltage may occur in the circuit due to other factors. This overvoltage may cause serious damage to electronic components and even lead to system failures. TVS diodes, through their instantaneous response characteristics, can quickly conduct when the voltage exceeds a predetermined threshold, diverting excess charge to ground and protecting other components in the circuit from damage.

TVS diodes can also effectively suppress electromagnetic noise in circuits. In some high-frequency applications, electronic systems are susceptible to electromagnetic interference, which may result in signal distortion or decreased device performance. TVS diodes not only protect the circuit, but also reduce the interference level in the circuit and improve the anti-interference ability of the entire system by absorbing electromagnetic noise.

TVS diodes have the characteristics of fast response and high power tolerance, making them effective in various complex electrical environments. This highly reliable characteristic makes TVS diodes an ideal choice for protection circuits, especially in scenarios that require rapid response between transients, such as lightning strikes or power supply emergencies.

In some applications with strict requirements for volume and weight, the miniaturization design of TVS diodes is particularly important. Its compact packaging allows TVS diodes to be easily integrated into various circuit boards without taking up too much space, which helps achieve miniaturization and lightweighting of electronic devices.

The long lifespan and stability of TVS diodes are another reason why they are highly favored in protective boards. In some fields that require extremely high equipment lifespan and stability, such as medical equipment, aerospace, etc., TVS diodes can ensure long-term reliable operation of circuits, reduce maintenance costs and fault risks of the system.

The role of TVS diodes in the protection board is not only reflected in preventing overvoltage damage to the circuit, but also includes suppressing electromagnetic noise, fast response, miniaturized design, long life, and stability.
