8D511J35AN

8D511J35AN is a kind of product range of thyristor surge protectors (TSPs) which is designed and manufactured by Littelfuse. Based on the principle of over-current protection and avalanche breakdown countermeasures, the surge protection device is an array voltage clamping equipment. It can provide a low impedance path for fast over-current, thereby limiting the overvoltage caused by high frequency current and lightning strike to device, ensuring stable performance and protecting the service life of the device.

TSPs are mainly used to protect various electrical and electronic equipment from sudden over-current and over-voltage caused by lightning strikes and other factors. 8D511J35AN is mainly used in the power and communication external circuit networks for lightning protection, transient over-current protection and AC/DC transient voltage protection. It is used for power network protection, customer networking protection, and electrical and electronic integrated circuit protection for all kinds of lightning arrester systems. The core components of 8D511J35AN are thyristors, multilayer ceramic capacitors, resistors, inductors, etc. With an ultra-fast response time and unique temperature compensation control technology, 8D511J35AN can effectively protect the electricity and communication devices from lightning strikes and transient overvoltage.

Working Principle of TSPs

The core of the 8D511J35AN surge protector is a voltage sensitive thyristor. When it encounters an overvoltage, its conduction angle will increase, its internal resistance will suddenly decrease, thus opening up a low impedance conduction path to provide fast over-current protection. When the voltage drops to a certain value, the conduction angle decreases and the resistance recovers, and the conduction path is closed. At the same time, a spark gap is provided to divert the lightning current to ground by avalanche breakdown. This enables the independent and reliable protection of the 8D511J35AN.

The 8D511J35AN surge protector has a wide operating temperature range from -40℃ to +105℃, and its installation mode can be either type II or type III. Type 2 surge protector is usually installed in the protected cabinet, while type 3 surge protector is usually installed in the power distribution cabinet. In addition, it also has the advantages of low insertion loss, fast response time, good temperature stability, and low failure rate.

Conclusion

The 8D511J35AN surge protector is playing an increasingly important role in network signal thunder and lightning protection. It is mainly used to protect various electrical and electronic equipment from sudden overcurrents and overvoltages caused by lightning strikes and other factors. With its reliable performance, wide operating temperature range and low failure rate, the 8D511J35AN has become a first-choice lightning protection device for many network and communication systems.
