Talk:Diode modelling

message: Glad to see this article is coming along. Here are a few issues that I think may need addressing:
*The article sounds a bit too informal. Some parts may need to be re-written to sound more "encyclopedic".
*ID >> Is seems like a better condition than Vd >> nkT/q for neglecting the - 1 term in the Shockley model.
*Also nkT/q is usually written as just VT.
*The plots should be redone as .png's to avoid artifacts
*The schematics could probably be redrawn as well.

replies: text: plots and schematics are even better drawn as .svg so they can be viewed at any resolution. Em3rgent0rdr (talk) 18:09, 6 July 2023 (UTC)

message: This article continues the myth that there is a Threshold Voltage in the forward V/I curve, however as the curve is essentially an Exponential, there can be no threshold, ie the rate of change is smooth and continuous, there is no elbow. Draw it on a Log scale and the "elbow" disappears. The idea of an Offset Voltage comes from a simple piece-wise approximation that is taught to students and technicians, but is then taken as gospel. The Threshold Voltage does not in fact exist. Gutta Percha (talk) 06:59, 17 September 2013 (UTC)

message: The word "ideal" to describe a diode can be very ambiguous. For one, we have the exponential Shockley diode equation which is sometimes called the "Shockley ideal diode equation" with its ideality factor n equals 1. But however this article currently describes a "Mathematically idealized diode" as to be something *very* different:
==== Mathematically idealized diode ====
Firstly, consider a mathematically idealized diode. In such an ideal diode, if the diode is reverse biased, the current flowing through it is zero. This ideal diode starts conducting at 0 V and for any positive voltage an infinite current flows and the diode acts like a short circuit. The I-V characteristics of an ideal diode are shown below:
And then later in this same article it describes a couple variants that use this "ideal" diode as a starting point.
I would suggest that this article refrain from using the word "ideal" unless it specifically is talking about the "Shockley ideal diode equation", to avoid confusion.
So this section "Mathematically idealized diode" should instead be called "infinite step response diode approximation"?  Because what it really looks like is the Heaviside step function multiplied by infinity. Em3rgent0rdr (talk) 17:34, 6 July 2023 (UTC)
