Forum rules:Click here to view the forum rules

  1. Topic title should contain: the device's manufacturer, full model and the brief description of problem.
  2. Topic message should contain: the PCB marking code (required in case of hardware repairs), an extended description of problem, things you have checked/replaced/measured, your conclusions and the question. If you are not able to find the PCB marking code, please read THIS TOPIC. If you still cannot locate the PCB markings, please upload a clean, both-side photos of the mainboard - it is required to remove any films, modules or brackets possibly covering these markings.
  3. Before posting a new topic please read all topics in TRAININGS subforum and make a preliminary diagnostic based on the content of those trainings.
  4. Uploading of any complete schematics, BIOS / firmware files or any other kind of documentation, or linking to 3rd party websites with such files, is STRICTLY PROHIBITED. You can only upload the small portion of documentation or, link to BIOS file on UNVERIFIED BIOS FILES subforum, which simplifies the diagnostics/repair. You are not allowed to upload more then one complete page of instruction/schematic per single topic. The file you upload must not contain any watermarks, "confidential" markings, links or email addresses and cannot be password-protected.
  5. It is only permitted to describe one faulty device per single topic - you should always open a new topic for each subsequent device.
  6. Requesting of the full schematics, BoardView files, BIOS files or any other kind of documentation is NOT ALLOWED in this subforum. If you need to ask for any of these, you should open a new topic in DOCUMENTATION/BIOS REQUEST subforum.

Zwarta dioda prostownicza (spadek napięcia w obie strony 0V, rezystancja 0,3 Ohm), w jaki sposób znaleźć / dopasować właściwą diodę prostowniczą (ta ma oznaczenie VSB3200 M014A).

Hello!
Find the data sheet of your original diode (VSB3200) and read the most important data from it. These are the diode type, max. repetitive peak reverse voltage and max. average forward current.
In your case they are:
Diode type= Schottky rectifier
Max. repetitive peak reverse voltage= 200V
Max. average forward current= 3A

Note that the max. repetitive peak reverse voltage and max. average forward current of the replacement diode may also be greater than the original one, but not smaller.

Go to the website, where you want to buy the replacement diode, for example TME.
Find all Schottky diodes available: Go to the "Semiconductors" -> "Diodes" -> "Schottky diodes" -> "THT Schottky diodes" and now enter the most important data to the "Filters":
Type of diode= Schottky rectifying
Max. off-state voltage = Max. repetitive peak reverse voltage= 200V or more (enter >=200 in the box)
Semiconductor structure= Single diode
Load current= Max. average forward current= 3A or more (enter >=3 in the box)

According to the data entered, you should find about 200 suitable replacement diodes. But you probably also want the replacement diode in the same package as the original one, so also select the Case DO201AD in filters and click to the button "Show products". Now you have only two suitable replacement diodes in the same package as the original one - they are NTE648 or NTE573-2.
