I wasn't going to stick my neck out but...What works for us
before a new official
footprint name was created...

We use Orcad Capture for schematic entry and spice modeling. Protel for
layout.

and what is rule #2 ? :}
personally, i oscillate between liking the 1 2 3 convention
and the E B C convention
like many things 'it's all bad'
i once had some T1 3/4 LEDs from HP
the short leg was the anode for that *particular* p/n
which is why they weren't very bright when installed

Dennis,
The pin numbering can only be 1 2 3.
Mira,
In Protel, pin numbers do not have to be numbers, they can be letters. So
you can use E,B,C for numbers if you want. If you have very commonly used
parts making a matching set of Sch and footprints with
Hi Ian,
I understand your point but I meant that
3
1 2
was the way you count the pins and it also showed the
direction.
I thought we were talking in general becasue 1 2 3 can
be also
2
1 3
What function will be attached to these pins depends
on the component and it can be a letter or a number

when we say 'different pinouts' are we talking about the
the geographical location of the given pin function or are we talking
about the pin *number* assigned to the given geographical location ?
it makes a difference!
anyway what is clear from this dialog is that we all care about what
we do

I have seem prototypes with SOT-23 upside-down
When you organise your footprints, what pinout do you use for SOT-23's?
Do you organise the pins...
-like shown in the attachment?
-or with pins 23 reversed?
The bigger question really is: Where do you derive your pin numbering
guidance from?
I find that some datasheets just show the pin

Hi Dom,
The basic numbering is
3
1 2
However many other variants of the pinout exist out
there.
Rule 1: Always check the datasheet.
