Hello all...I am repairing a high voltage glassman power supply. I found 2 diodes blown but I cant figure out the value even I google it. It looks like it in the voltage doubler circuit with capacitor rating 0.002uF/6.5KV. Is there any way we can identify the diode value/rating? thanks

I suppose you have a service manual for the power supply ? They usually provide circuit schematics and parts lists. If not possibly writing to the manufacturer might yield some results.

Here's one manual which I found online

Try use a CL01-12 they are pretty cheap and common and they are good for 12KV.

Thanks a lot for the time spent searching the manual online...I just opened it I cant see high voltage diode from the schematic but there's no value.

Ok great...let me purchase this one and try...it should probably work with 15KV output....thanks
 

those numbers look like date codes - what else is on the devices?

Yeah they are tough diodes, but you can always put two or more in series if you need much higher voltages.
