Where is this diode manufactured? Generally, manufacturers have different conventions in marking this diodes. If I were you, you could do some testing if you have a multimeter. In that way you can know the characteristics of the diode.
This diode is out of a power supply in which we do not have an manufacture information on the diode. The diode can not be measured because it has failed and is shorted
Well that is unfortunate. What is the output voltage of the power supply? The diode could be a zener type and used for voltage regulation. Knowing this, can help you find a replacement for this component.
