@dick_freebird I missed mentioning the diode resistance value when it is in a failure state. It mostly ranges from 2 K to 7K, But it is consistent if no external forces (temperature) are applied.
I experimented with a problem PCBA. I removed the cap and ferrite using a wire stripper, isolated...
Yes, I removed all the traces to the diode on the PCB and baked it and it fixes the issue. Even if I blow the hot air/apply a soldering iron to the diode it fixes the issue. In the diode construction, there is a layer of this diode, which is epoxy and maybe it is prone to moisture absorption...
Would conductive anodic filament (CAF) formation occur internal to the Diode? Are there any technical papers related to that? I am facing a component failure unrelated to ESD and after exposed to high temp (45C) and low humidity (6% RH) conditions, the issue is getting resolved. The diode is...
