TVS-Diodes

TVS-diodes, also known as transient voltage suppressors, are one of the most important components in modern electronics. They serve as a safeguard against voltage surges, electrostatic discharge, and lightning strikes. They can be used to protect circuits, components, and systems from potential damage caused by these types of events.TVS-diodes are two-terminal devices that combine several protection structures in one unit. The 824500581 is an example of such a device and includes a variety of technologies to provide an effective solution for the protection of sensitive circuits. The 824500581 consists of integrated silicon-controlled rectifiers (SCRs), avalanche diodes, and Gas Discharge Tubes (GDTs). Each component of the device is connected in parallel with a surge current path to provide the protection against transient currents. The SCRs act as a switch in the device, allowing current to flow in uncontrolled bursts when triggered by a sudden voltage change. They are typically used in circuits to provide overvoltage protection or surge protection. The avalanche diodes are similarly used to provide protection from high-voltage spikes, offering relatively low breakdown voltage and fast response time. Finally, the GDTs or spark-gap tubes use air-filled tubes for protection from high-voltage transients. A spark-gap tube consists of two electrodes and a surrounding mixture of air and vaporized metal ions. When a high-voltage surge is applied, the ionized air in the spark gap creates a conducting channel that allows a controlled discharge, limiting the surge current and voltage levels to a safe level.The 824500581 is designed to handle a wide range of surge currents, while providing low-capacitance and low-inductance protection. Its maximum peak pulse current capability is rated at 216A for 8/20 microseconds. It can handle a breakdown voltage of 20V and has a typical clamping voltage of 27V. The 824500581 also has a maximum capacitance rating of 70pF, making it ideal for EMI/RFI filtering applications. In addition to its overvoltage protection capabilities, the 824500581 also offers ESD protection up to 20kV per IEC 61000-4-2. The device is also resistant to temperature cycling tests (-55°C to +175°C), gravity, humidity, and vibration test, making it highly reliable and robust. TVS-diodes are used in a wide range of applications, such as consumer electronics, automotive systems, industrial control systems, military, and aerospace systems. Their robust construction and protection capabilities make them ideal for situations where reliable protection is needed. The 824500581 is a versatile device that can be used in a variety of applications to protect against electrostatic discharge, lightning strikes, and high-voltage spikes.

Conclusion

The 824500581 is an effective protection device from TVS-diodes, combining advanced protection structures to protect against voltage surges, electrostatic discharge, and lightning strikes. It is designed to offer a wide range of protection features, including high peak pulse current capability, low-capacitance and low-inductance. The 824500581 also has a high ESD rating. Its rugged design and construction makes it suitable for a variety of applications, including automotive systems, military, and aerospace systems.
