Introduction

IMN11T110 is an 11-pin surface-mount dual 2-string array that protects a network\'s infrastructure against lightning discharges. Developed by INFINEON Technologies, this diode rectifier array signals overvoltages and provides fast dv/dt protection as well as bidirectional propagation. As a surface-mount device, its small size benefits applications where a large number of diodes are required and where space is an issue. IMN11T110 is designed for in-line protection and can be integrated into telecom, industrial, automotive and consumer applications.

Application Field

IMN11T110 has been designed for use in the protection of communication equipment such as Ethernet, power over Ethernet (POE), optical transceivers and other communication systems. It is ideally suited for high-performance applications such as Telecom and datacom systems where its fast-reacting protection capability is essential. Moreover, it is well-suited for use in TV co-axial antenna systems, while its high power output allows it to be incorporated into power over Ethernet (PoE) applications.

Working Principle

In any application, it is the diodes within the IMN11T110 package that actually provide the protection to the network’s infrastructure. This is why it is important to understand the operating principle of the component and how it functions to provide protection. When struck by lightning, the voltage of an input signal will surge significantly, causing it to exceed the diodes\' reverse breakdown voltage. As this happens, the diodes effectively switch states, redirecting the surge and protecting the input signal from damage. The IMN11T110 diode rectifier consists of two strings of five diodes, which help to reduce the voltages of incoming signals. This is because the previous surge is divided between the diodes as more voltage current is allowed to pass through the component. Moreover, the device is designed to handle up to 20KV very quickly, so the user can be assured of its protection capabilities. Furthermore, the component can handle up to 125A of current, and hence, can be used in applications that require higher levels of current. This makes the component suitable for applications such as the power over Ethernet (PoE) or telecom and datacom systems.

Limitations

Like all electronic components, the IMN11T110 has its limitations. One key limitation is that it is only capable of handling high voltage transients within short periods of time. Therefore, it may not be suitable for applications that require prolonged high-voltage protection, such as industrial automation systems. Moreover, it has a limited capability to handle constant high voltage over a long period of time. Another limitation is its limited temperature range of -40°C to 150°C. This is because most telecom applications are designed to operate in a wide range of temperatures, so an extended range may be required.

Conclusion

To conclude, the IMN11T110 is an 11-pin dual 2-string array that is used for protecting networks against lightning discharges. It is designed for use in applications such as telecom, datacom and power over Ethernet; and its fast-reacting protection capabilities make it an ideal choice for these applications. However, it should be noted that the component has certain limitations such as its inability to handle sustained high voltages, and its limited temperature range. Despite these limitations, the IMN11T110 remains a reliable diode rectifier array and can be effectively utilized in the protection of communication networks.
