Article 8: TVS diode anti-static design guide: Best solution for consumer electronics interface protection

The USB interface, headphone interface, button port, and communication interface are the most vulnerable locations for electronic products to be damaged by static electricity. Reasonable arrangement of TVS diodes in hardware design is the most cost-effective and effective anti-static solution.

Design points:

1. TVS should be placed as close as possible to the interface position to shorten the discharge circuit;

2. Select low capacitance TVS for the signal port to avoid affecting signal integrity;  diode

3. The power port uses high-power TVS to resist surge and overvoltage.

Common applications: power banks, Bluetooth earphones, smart homes, car devices, industrial control communication ports.

Mass production experience: The low-cost TVS protection solution can reduce the static repair rate of products by more than 90%, making it an essential design for standardized protection in consumer electronics. diode
