Hello Everyone,
I have 1 diode on a circuit that I suspected to be faulty because the forward and reverse bias has a voltage drop reading.
While compared to the reading of another diode from the next channel it won't read at reverse bias.
Now the problem is; it does not have any body marking.
So I tried to sketch the diagram and found out that it is connected to the base and collector of the C3632 transistor.
What do you think is this diode?
Can you please suggest what part number can i use to replace this faulty diode instead?
Hoping that you... -
Hello,
im actually trying to save a d1500 delay from yamaha. I found the service manual but schematic is missing and BOM list is a bit unclear as components listed have no reference linked to the pcbs... In my case, one zener diode was broken (114 code on the pcb in attached file) and couldn't be repaired : it was a zener type package. In the BOM list i found 3 reference on this board : 1S555 (can be replaced by 1N4148), RD4.7EB2 (approx 5v rectifier), RD7.5EB3 (approx 7v rectifier)...
Actually the cathode goes to VCC of sram M5M5118P, without this diode missing, i have... -
Hello.
I need help in identifying a component. It appears to be 3 pin fuse, marking SEFUSE D5T4YB, but i cannot find any information about it. Taken out of DELL XCMRD 14.8V battery board.
Thanks in advance.
Edit: Got told its D6T, because there was still more gunk on it. Sorry for bother and thanks.01-31-2025, 12:58 AM -
This diode is mounted on a Frigidaire electronic oven control PN:316131600. This diode runs hot enough that the PCB is showing slight burn marks (black soot looking area on PCB above the diode). It looks to me to be coming from the body of the diode.
The oven control is 22 years old and still works, but I can't get a new replacement, so I'm doing preventative maintenance and replacing a few parts on it that I think could fail - and this is one of them.
Can any of you identify this diode (see pic) and suggest a replacement that can handle more heat - or if not, can... -
Hi there all.
Troubleshooting an SMPS and I’ve found a SMD diode shorted in both directions. The trouble is it has no identification on it. So what do I replace it with and how do I tell where the anode and cathode is and how to mount the replacement?
It is diode D1 on the image.
Regards.
