Is there a meaning to colors on a transitor?

[RAPo]

I've got a whole collection of (unclassified) transistors.
I'll know that a dot on it can mean it is a matched pair.

But I also have transistors with several colours.


Do these colours have a meaning?

[Psi]

Yes, its just the part number without the prefix, like 2N etc..
Colors are the same numbering as resistor colors. So red red red red would be 2N2222 etc...

Ah, thanks. That makes the classification job easier. Topline color = first digit?

[Benta]

Please show the other side of those transistors. The "colour-code" hypothesis is not really credible to me.

I know those coloured stripes as ranking for h_FE or I_DSS, not the actual part number.

I think you are right. There are several A06's but they have different colours

Do you have more info on which colour is used for which property?
