100M Ethernet Port Protection Solution

Application Background

Global warming is leading to an increase in thunderstorm weather
Damage to network equipment caused by lightning strikes can be highly hazardous
After lightning damage to network equipment, the maintenance cost is high
High surge protection equipment has become an industry trend

Plan description and precautions
This scheme employs GDT for common-mode (four-wire) surge protection at the front end of the transformer
The downstream stage of the network transformer utilizes a TVS with small size and low junction capacitance to absorb differential mode energy. The TVS has a fast response time and also serves as an electrostatic protection function
Complies with 802.11 electrical standards
Meets surge testing standards such as IEC61000-4-5 and GB/T17626.5
Meets electrostatic testing standards such as IEC61000-4-2 and GB/T17626.2
