Hi,
I have a little problem of understanding dark current.

Is dark current the same as reverse bias current of a photodiode?
If there are some other sources of dark current, such as detects in silicon..etc, what are the portion of reverse bias current that contributes to dark current?

Thank you!

Re: Dark current!

dark current is reverse current which is maximum reverse current in minimum intesity of light
miority carriers also contribute in dark current.
 

Dark current!

total current - photocurrent = dark current or reverse current
