1. The problem statement, all variables and given/known data
Hi, I have a problem to find the reverse saturation current for a piece of diode. I have a question  given conductivity, a IV curve with forward bias information (a table of I vs V values), how can i proceed? I have other information abt the diode such as its mobility, and then it is made of silicon  other material info assume given. Anyone can advise the approach? thanks. 2. Relevant equations 3. The attempt at a solution

If your data are precise, substitute the values of one point of the curve (VI) into the diode equation and obtain Is. If your data are real, they should have measurement errors and you should use the diode equation in conjunction with a filter to obtain Is.

Use the Shockley Diode equation, that should yield an answer.
