Finding reverse saturation current.

AI Thread Summary
To find the reverse saturation current (Is) for a diode, substitute the values from a specific point on the I-V curve into the Shockley diode equation. Given the conductivity and mobility of the silicon diode, accurate data points are essential for precise calculations. If measurement errors are present, apply a filtering method alongside the diode equation to refine the result. The approach hinges on the quality of the I-V data provided. Utilizing the Shockley equation will yield the necessary reverse saturation current.

Homework Statement



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.

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