DIODE Identification

[b9creations]

Hello,

Looking to identify a diode on a circuit board, and can't make out the numbers= unreadable.

Is there a way to test a diode to see what it's properties are? Or is wattage determined by size somehow?

Size of the tube body is .200" x .104" lead wire size is .032"

I assume this might be something standard and easy to figure out?

Thanks for the help!

it is easy to measure with an applied voltage thru an appropriate sized R.
Case size denotes power from any datasheet.

Thanks SunnySkyguy! Good to know I can get to the bottom of this. I assume I will have to disconnect one of the leads to get an accurate reading then?

Yes, you would have to disconnect one end to isolate it from the surrounding circuitry but then you would probably be able to read the whole number on it anyway. Unfortunately for you, that is a standard diode package and there are thousands of different kinds that look the same. Some tests will give clues to it's type if you can't read it but here are many duplicates from different manufacturers and the measurable parameters often overlap each other. I'm afraid it can be like finding a screw on the road and trying to work out the license plate number of the vehicle it fell from!
