I warmly welcome What to replace the T25-4-H0 diode from the car rectifier bridge with start-up? The diodes burned out this diode T25-4-H0 has a cathode or anode on the wire? Diode as in the picture

A colleague should check this by nature - by viewing / measuring the rectifier circuit. No information (catalog note) for these LEDs. Uncertain information - no known polarity of the original diode, unknown current / voltage.

Hello, I had a similar bridge on four diodes. 3 diodes are T25-4-j3 and one T25-4-C4. And it turned out that these T25-4-J3 had an anode on the wire and the one marked T25-4-C4 had a Cathode on the wire Maybe someone will need this information.

I warmly welcome

What to replace the T25-4-H0 diode from the car rectifier bridge with start-up?

The diodes burned out

this diode T25-4-H0 has a cathode or anode "on the wire"?
