does anybody no the spec on this diode

need to raplace but never seen one like it before there was three al burnt up becuase caps went bad so dont no their values

Please remove the diode from the board and give us a close up image of all the numbers on it .

of course you do not have the schematic do you. Problem is - are they just plain diodes or are they Zeners, or are they Varactors - hmmmmmm. Are they in the power supply circuit or maybe in signal conditioning circuit??

If I had to guess at a diode - I would most likely try a plain ole generic - like a 1N4004. Not the same size but would work if the diode's job is to rectify.

Really need to know the function of the diode.

It appears to be a switching power supply. I suspect this because the white diode at the top of the picture looks like a high speed switching diode and it is mounted on long leads for heatsinking.

The diodes in question may be high speed types. That is, fast recovery diodes. Determine the voltage rating of the capacitor the diodes drive, multiply by three or four (or more), and chose a diode that is rated fast recovery, the voltage determined, and 1 to 3 amps. And, they may be Schottkey diodes, which are inherently very fast.

theres no numbers only the stipe and three dots or four and this symbol on the board its power a exteranl relay with power around 12v

cap 1v 330uf

10v 330uf
