Need to create a spice model for a static induction transistor? Now you can digitize a graph of IV characteristics from a photo taken from a datasheet, web image, or a picture of your curve tracer screen! Then, take your digitized data to the SIT Curve Fitter and the parameter extraction happens automatically. Create SIT models in two easy steps. Check it out here: SIT Curve Fitter There’s one for Triodes too: Triode Curve Fitter
