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.

Prueba el diodo TVS

El diodo TVS, marcado con D6 e la PCB, esta localizado entre la antena y un gran IC en el puerto RJ45 a lado de la tarjeta.

Es un diodo TVS unidireccional de 24V con cable J (SMBJ24A) hecho por Littlefuse. Nota el lugar de la barra blanca en el diodo, ya que indica su orientación.

Usa un multímetro o óhmetro para probar si el diodo esta en corto. Un diodo en corto marcará una lectura de 1 Ohm en ambas direcciones. Un diodo funcional tendrá resistencia significativamente más grande en una dirección que en la otra.

Si el diodo no esta en corto, entonces debe de haber otro problema, y seguir adelante no ayudará a resolver el problema con tu punto de acceso.
