S3V00 DIODE?? LAMBDA JWS75-12iA Switching Power Supply
« on: September 18, 2020, 06:25:12 pm »
Okay, I realize the power supply probably isn't worth fixing, but I like to try things because of the challenge.

In the primary of the first switching transformer there is a 82uf 470V 105c cap that is basically open.  The consequence being the a larger axial thru-hole diode that appears to feed voltage to the transformer is shorted.

The only nomenclature on the diode is "S3V00".  Maybe that is a TVS3V00?  Either way, my googling skills are not good enough to find any data on the diode.

Does anyone here know what that diode is?  Guessing, I would say maybe 3 watts.

My googling skills are not good enough to locate a schematic for the power supply either.

I think, for expediency, I will replace the power supply, but I would still love to fix it.
