I've been modeling an LED (in Eagle) for a high school class I'm teaching. I found this "file" and imported it into the general diode model. It works, but doesn't exactly match values that I measure on a breadboard.
*Red LED
.MODEL DMOD D (IS=93.2P RS=42M N=3.73 BV=4 IBV=10U
+ CJO=2.97P VJ=.75 M=.333 TT=4.32U)
.MODEL DMOD D
The model puts out a Vf=1.8v for 20mA, and Vf=1.7v for 7mA.
I'm probably splitting hairs, but I'm just trying to understand what all those values in the model mean.
