Finding reverse saturation current.

  1. 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 I-V 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.

  3. Where is the relevant equation?
    If your data are precise, substitute the values of one point of the curve (V-I) 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.
  4. Use the Shockley Diode equation, that should yield an answer.
