It may or may not suit your purpose. More can be found at: https://en.wikipedia.org/wiki/Diode_modelling#Shockley_diode_model -------------------------------------------- If you want a simple V-to-I formula... I wanted to find a mathematical equation to model a diode for purposes of simulation. I performed many tests on diodes with my meter, and then plotted the data, and tried to fit an equation to the graph. I came up with: A = ( V x 1.25 ) ^ 20 This is only for a typical silicon diode. It will require a different equation to model an LED or a germanium or a schottky or a power diode.
