diode voltage

[orange]

just a quick question, maybe a little bit offtopic (sorry):
If a diode current is 15 microAmperes (forward), what is the voltage?
I need an answer as close to 'real life' as possible.
Its a silicone diode, 1N4148 or similar

This varies alot by the part number. I'll show you how to fish...

The datasheet for your part is here:
http://www.diodes.com/datasheets/ds12019.pdf

If you look under electrical characteristics at "Maximum Forward Voltage",
you'll get a worst case.

Scrolling down to page two, the first graph tells you exactly what you're
after.

Also, there are several differenct package types for this diode. Best to
lookup the data sheet for the one you're planning on using.

No, it's not.

As has been said, to find the characteristics of a SPECIFIC part
get the datasheet for THAT part.

[...]1N4148 or similar

If you are really looking for "close",
a "similar" part will result in a *different* answer.

It is temperature dependent.

Look in the data book or measure it.

It is temperature dependent.

Diodes are actually used as temperature sensors in some cases.

1 voltmeters a resistor the diode and a power supply.
