Ethernet technology is characterized by simplicity, efficiency and low cost.With the rapid development of Ethernet in recent years,the variety of services it carries has increased, and Ethernet broadband and rates have grown by leaps and bounds.Outdoor Ethernet is prone to lightning strikes. In order to ensure the effectiveness and reliability of Ethernet, it has become an industry trend to provide high-surge protection for equipment.As a circuit electronics components supplier with many years of surge protection experience, Socay has designed a protection solution for Gigabit Ethernet.

Socay Electronics Components

Gas Discharge Tubes(GDTs)

GDT【SC1206-200ASMD】DC Spark-over Voltage：200±30%V，Nominal Impulse Discharge Current（8/20μS）：0.5kA，Maximum Capacitance＜0.5pF，Minimum Insulation Resistance >100MΩ; 

GDT【SC1812-90CSMD】DC Spark-over Voltage：90±20%V，Nominal Impulse Discharge Current（8/20μS）：2.0kA，Maximum Capacitance＜1.0pF，Minimum Insulation Resistance >1GΩ

TVS diode 

TVS【ESD03V32D-LC】Vrwm：3.0V；Vb：4.0V；Vesd：8KV/15KV；Ct（f=1MHz）：1.2pF；Package: SOD-323

Solution Application

1. Laptop, PAD, home desktop computer, industrial computer

2.Switches/Router

3.camera equipment

4. Network printer

5. Set-top box

6. intelligent transportation system

7.Other devices with Ethernet ports

The Solution Note

1. The solution uses GDT in the front end of the transformer to do common mode (eight lines) surge protection.

2.The back end of the network transformer uses TVs with small volume and low junction capacitance to absorb differential mode energy. The TVS has fast reaction time and takes into account the function of electrostatic protection.

3. Comply with 802.11 electrical standards.

4. Meet IEC61000-4-5, GBT17626.5 and other surge test standards.

5. Meet IEC61000-4-2, GBT17626.2 and other electrostatic test standards
