Did you fail those symbol-matching IQ problems in grammar school?:D

I thought it was settled as a zener diode?

Looks like the voltage limiter may be two back-to-back zeners.

I assumed that the dark coloured are in the symbol could be a polarity indicator. . .

If we look at the symbol for an electrolytic capacitor, there are several different variants, but all mean the same thing.

It was just a suggestion of a possible component.

If I caused offence with my stupidity, then I apologise. If I made you laugh at me, then ok.

Do people understand that there are more shapes than just bold lines and triangles? If I designed a component I would make it look cool.

I didn't intend to offend you. I was just having a little fun - at your expense, I guess. :( I assumed you had posted an answer without reading the entire thread. I believe it has been established that the symbol represents a zener diode.

Here's another one to ponder, maybe it is a Shockley diode? Is there a need for a latching action in the circuit?

Granted the "normal" symbol is more like half of what you have, but this is the only symbol I know of that is like this.
There is no need for hysteresis in the circuit, although it might work. As I said above, I believe we have established that it's an (old?) European symbol for a zener diode.
 
Hi Ron.

You didn't really offend me. I'd just been having a bad day. And I did skip some of the replies to the thread.

I don't understand why we still use different symbols to represent the same components (US symbol for resistor vs. european symbol for resistor), or the different symbols for caps.
If we all used 'Industry Standard' symbols things would be much easier.
I suppose it gives a good discussion topic anyways.

Do we mean USA Industry or Japanese or Chinese or one of the european ones?

(Whatever happened to Avalanche diodes ?)
 
I found the second link with the Image Search feature of Google.
Then I used another search engine (Yahoo?) and found the first link.
