I have a diode where one leg is sheared of flush. I am getting different readings everytime i test it with multimeter. I want to replace it and make sure i use the correct diode...i get readings from .545 to .552

Looks like you're measuring the junction drop. That won't tell you the important stuff like how many volts it can handle.

Can you clean up the part a little? It looks like you can almost read the number on it.

They are usually something like 1N4001.
 
Looks like your typical silicon rectifier diode (replace with a 1N4007). Like Phil said, we'd know better if you told use where it came from.
 
Measuring voltage drop tells you nothing for a rectifier. (Zener would be different; that has relevance).

Black body diode. Small. White text.
Likely a common 1N400x diode.

Where's it from? Which board?
