Test the TVS diode

  • The TVS diode, marked D6 on the PCB, is located between the antenna and a large IC on the RJ45 port side of the board.

  • It is a 24V uni-directional TVS diode with J leads (SMBJ24A) made by Littlefuse. Note the location of the white bar on the diode, as it indicates its orientation.

  • Use a multimeter or ohmmeter to test whether the diode has shorted. A shorted diode will read less than 1 Ohm in both directions. A working diode will have significantly higher resistance in one direction than the other.

  • If the diode is not shorted, then there may be another issue, and proceeding further may not help resolve the problem with your access point.

Testez la diode TVS

La diode TVS est située entre l'antenne et un grand circuit intégré du côté du port RJ45 de la carte. Son marquage PCB est D6.

Il s'agit d'une diode TVS unidirectionnelle LittleFuse 24V, avec fils J (SMBJ24A). Notez l'emplacement de la barre blanche sur la diode, qui marque son orientation.

Utilisez un multimètre ou un ohmmètre pour vérifier que la diode a effectivement court-circuité. Une diode en court-circuit lira moins de 1 Ohm dans les deux sens. Une diode de travail lira une résistance significativement plus élevée dans une direction par rapport à l'autre.

Si la diode n'est pas court-circuitée, alors quelque chose d'autre ne va pas, et continuer peut ou non aider à réparer votre point d'accès.

[title] Test the TVS diode
-[* orange] The TVS diode is located between the antenna and a large IC on the RJ45 port side of the board. It's PCB marking is ***D6***.
- [* black] It is a LittleFuse 24V uni-directional TVS diode, with J leads (SMBJ24A). Note the location of the white bar on the diode, which marks its orientation.
-[* red] Use a multimeter or ohmmeter to test that the diode has indeed shorted. A shorted diode will read less than 1 Ohm in both directions. A working diode will read significantly higher resistance in one direction relative to the other.
- [* icon_note] If the diode is not shorted, then something else is wrong, and proceeding further may or may not help fix your access point.
