Curve fit a function for Diode Vf(If) that works with units

12-13-2014 11-33-14 AM.pngHello all,

I am trying to create a function that gives Vforward for a diode as a function of Iforward.

Start with a log fit based on a series of data points taken from a datasheet which gives three coefficients to build the function.

The function works fine if i keep eveything unitless, however I would very much prefer if the function takes current (A) and returns voltage (V)

Any suggestions on how to modifiy the coefficients to achieve this?

Thanks,

David

In the rhs of the function definition divide I by A
