Understanding Transient Voltage Suppressors (TVS) in Electronics


 


Transient Voltage Suppressors (TVS), commonly referred to as TVS diodes, play a crucial role in safeguarding electronic components by mitigating the impact of transient voltage spikes. The electrical characteristics of TVS devices are determined by factors such as the P-N junction area, doping concentration, and chip resistance.

  • Electrical Characteristics and Applications:

The ability of a TVS device to withstand surge currents is directly proportional to its P-N junction area. These devices find extensive application in the protection of semiconductors and sensitive electronic components, serving in secondary power supplies, signal circuits, and electrostatic discharge (ESD) prevention.

  • Key Features:

TVS diodes are characterized by their rapid response time, typically in the picosecond range, making them highly effective in suppressing transient voltage spikes. They are compact in size, providing a space-efficient solution for electronic circuit protection. Additionally, TVS diodes exhibit a high pulse power-handling capability, with pulse power ratings ranging from 400W to 30KW, and peak pulse currents spanning from 0.52A to 544A.

  • Versatility in Voltage Protection:

TVS diodes are available in a range of breakdown voltages, from 6.8V to 550V, catering to diverse circuit voltage requirements. This versatility makes them suitable for various electronic applications where protection against voltage transients is critical.

  • Applications in Electronic Circuits:

These devices are commonly employed to safeguard semiconductor devices, such as integrated circuits and sensors, from voltage surges. They are also utilized in secondary power supplies to prevent voltage spikes from damaging sensitive electronic components. Moreover, TVS diodes play a crucial role in protecting signal circuits, ensuring the reliability and longevity of electronic systems.

  • Conclusion:

In summary, Transient Voltage Suppressors (TVS) are indispensable components in modern electronics, providing robust protection against transient voltage spikes. Their compact size, rapid response time, and versatile voltage protection make them a key element in safeguarding electronic circuits from potential damage. As electronic systems become increasingly sophisticated, the importance of TVS diodes in ensuring reliable and durable operation continues to grow.

Contents 1. Introduction to PS/2 connector 2. PS/2 connector characteristics 3. Jingyang electronics' ESD/EOS protection solution for PS/2 interface 1. Introduction to PS/2 connector The PS/2 connector is an connector on a PC-compatible computer system that can be used to connect a keyboard and mouse. PS/2 is named after the personal computer launched by IBM in 1987: Personal System/2 (PS/2 series). This is a special connector for mouse and keyboard. It is a 6-pin circular connector but the mouse Only 4 pins are used to transmit data and power supply, and the remaining 2 pins are empty. It should be noted that when connecting to the PS/2 connector. When using the connector, pay attention to distinguish the mouse and keyboard connectors. The corresponding colors are as follows: Generally, for a motherboard that complies with the PC99 specification, the mouse connector is green and the keyboard connector is purple. In addition, it can also be judged from the relative position of the

·  Package Because TVS needs to dissipate a significant amount of energy, the physical size needs to be larger. Common packages: DO-214, DO-218, DO-15, etc. ·  Peak Pulse Power Dissipation It indicates the capability to dissipate the maximum energy, with the testing condition specified as a 10/1000µs waveform. This means that this metric is a specific testing methodology within the industry and is not arbitrarily added with DC testing. ·  Peak Pulse Curren It indicates the ability to withstand the maximum pulse current. If this current is exceeded, there is a high likelihood that the TVS may become damaged. ·  Peak Forward Surge Current It refers to the maximum positive surge current magnitude. However, please note the testing conditions: 8.3ms Single Half Sine Wave. This means it is not a direct current, but rather a waveform with a very short duration. ·  Parasitic capacitance The parasitic capacitance is a parameter that can impact the practical application of TVS. In the case of da
