>> Application background
1 Global warming, and the thunderstorm weather increased.1 This scheme uses GDT to do common mode (eight wire) surge protection at the front end of the transformer.
2 A low junction capacitance TVS removes differential mode energy at the back end of the transformer, meantime the TVS is used in the protection of static electricity with fast reaction time
3 Compliance with 802.11 electrical standards.>> Protection circuit diagram
