      Audio headphone port circuit protection
      Solution:
      Audio headphone port circuit protection
      Design description:
      Protection application:
      The maximum signal value of such audio lines up to 12 Vp-p, the operating frequency is less than 30kHz. At this frequency, without considering the capacitance of the suppressor. ESD electrical hazards exist.

      Solution description:
      As shown on the left, using discrete MLCV, so flexible layout. Since the audio signal has analog properties, it is recommended to use a single stage transient suppression diode array only when the signal negative value is -0.5V or more, because they can reduce the negative value of the audio signal when the value is large.

      Matching solutions:
      In addition to the above recommendations, the electronic tage MLV product portfolio also provides other solutions. For example, if a manufacturing process fails to handle components of 0402 specifications, a device of the same size as the 0603 specification may be selected.

      Regulatory issues:
      IEC 61000-4-2 is the most suitable standard for this interface. Through the test can prove that terminal products are not vulnerable to ESD hazards.

      Characteristic: not applicable.

      Application warning: not applicable.
