Thor RL2 450 - Diode for the rectifier with the symbol T25-4-J6

Question

I am looking for a T25-4-J6 diode, I searched the internet and nowhere can I find information or pages where it could be purchased, can these diodes be replaced with others :?:

I did not find any information on the Polish-language websites.
I know that I could buy a new bridge, but replacing the diodes themselves should be much cheaper.

This is what it looks like in full:

You have 2 options: either replace the 4 damaged ones with the same ones, or replace them all with the 60A that you found on Alle ... If you only replace the burned ones with a different type, it may happen that they will have a lower forward voltage drop, and then they will take over most of the current at start-up and will be damaged.

Wawrzyniec · Answer

Show what this diode looks like, because I can see that you have it pressed out. It is very possible that the alternator diodes will match.

No, there was no diode in this place, what alternative to use apart from this marking I have no data. This is what it looks like: On one of the auction portals I found similar 60A LEDs, the diameter of the base only matches whether other values match :?:

Wawrzyniec · Answer

How many sheets with LEDs do you have? Two?

mawerix123 · Answer

Four and six LEDs on each.

Wawrzyniec · Answer

What 6? I can see 4 diodes on 1 heat sink and 3 diodes on the other (1 missing). Is it a three-phase rectifier? Added after 4 [minutes]: Other values are voltage and polarity. What current and voltage does this rectifier give?

mawerix123 · Answer

In the first post I could mislead you, the photo is illustrative (it contains the same LEDs but comes from the welding machine). The rectifier is powered by 230V, charging voltage is 12 and 24V + starting. Here is the arrangement in question And here is the device plate

Wawrzyniec · Answer

I have not found the parameters of these diodes. How are they combined? All 6 together or 4 together

mawerix123 · Answer

It seems, depending on the taps, but after three aaa and I forgot to add the anode on the base beforehand.

DJ ANNUS · Answer

First of all, how many diodes are burnt, like 1, do not bother with it. Added after 4 [minutes]: These are regular half inch LEDs.

Wawrzyniec · Answer

Draw a diagram, you will know what to do with it because on seems to we can only suppose.

mawerix123 · Answer

Unfortunately, one of the three is left on the 12V tap, I suspect that they will not withstand the next start-up. Added after 1 [minutes]: And activity on Sundays, as I can see, I have I'll try to put together something.

Wawrzyniec · Answer

What does it mean ordinary? 20A, 35A, 60A or 100A? Added after 3 [minutes]: Then replace all of them with the 60A

DJ ANNUS · Answer

BYP 60a6 or BYP 60k6 these are publicly available. Although the originals are on 25A. A bit weak for a start-up.

Wawrzyniec · Answer

Depends on how the transformer is built. For full wave rectification it can be 6x25A, and for full wave rectification 12x25A At best, of course.

DJ ANNUS · Answer

Usually there is a full bridge for 24V to 12V, there is a tap in the middle of the winding, only 1 wire is switched, once to the center of the winding and once to the anodes of the negative diodes.
So there is always a 2-half straightening.

mawerix123 · Answer

I made a diagram of this bridge and there are six diodes: From the ones marked in red, only the base and the wire remain ...

mawerix123 · Answer

The rectifier works, we close
