Date：2025-12-08 Viewed：7

Application Background
■ Global warming, more thunderstorms
■ The damage of network equipment by lightning is serious
■ The cost of repairing the network equipment damaged by lightning is high
■ High surge protection equipment becomes the industry trend

Program Description and Precautions
■ This solution utilizes GDT to implement common-mode (four-wire) surge protection at the transformer's front end.
■ The TVS with small volume and low junction capacitance is used to absorb the differential mode energy at the back of the network transformer. The TVS has fast response time and can protect against static electricity.
■ Complies with 802.11 electrical standards
■ Complies with IEC61000-4-5, GB/T17626.5 and other surge test standards
■ Complies with IEC61000-4-2, GB/T17626.2 and other electrostatic testing standards

Application of the scheme
■ notebook PC
■ Home desktop computer
■ Industrial PC
■ exchange board
■ router
■ Gun equipment
■ network printer
■ Set-Top Box
■ Intelligent Transportation System
■ Other Ethernet port devices
