Missing Thyristor in core parts
Not to be annoying here, but I was tought that "thyristor" is a classification of some solidstate parts. So, I checked wikipedia (because, you know, if it is on the internet it is true). http://en.wikipedia.org/wiki/Thyristor Wikipedia seems to indicate there are a couple different interpretations of the term "thyristor". Is it an American thing to think of thyristors as a classification (which include SCRs, TRIACs, etc) instead of just being a SCR?
(Honest question of cultures here. Like asking who thinks of a "billion" as a "thousand million" or a "million million". see http://www.jimloy.com/math/billion.htm )
@Kuki, so what specifically were you asking for? All the components in the classification of thyristors, or just a Silicon Controlled Rectifier?
Also, what artwork is needed?
For now, you can get by with a 3-pin mystery part.
If you just want the breadboard and schematic to have standard symbols, say for an SCR, then that artwork is needed.
If you are more interested in the PCB, then there might be several more artworks required, for each package, for example a large hole for a high-power SCR that is threaded (and in that case I'm wondering how Fritzing routes to the vertical lug of the SCR.)
@bootchk
I think you've exposed one of the weaknesses of a library system that has a single piece of artwork across different views for a single part. (Which is why I like how KiCAD (for example) does their libraries with separate libraries for schematic and pcb. Even-though some people think it's an annoyance to have to choose their part "twice", once for the schematic and once for the pcb.) As I remember from other threads, multiple parts can call the same SVG artwork files. So, each package would have it's own library part, but all the SCR packages would reference the same schematic artwork symbol.
As far as the high-power SCR, (high power diodes are similar), I'm not sure how well Fritzing handles off-board connections. (The schematic part having a pin that isn't referenced on the pcb? Does that work in Fritzing, or would that break?)
