Help-Wrong footprint

[James]

I've used the wrong footprint for a SOT-23 NMOS logic fet

As a result I need to find a transistor that has the following pin structure:

[Source]

[Gate] [Drain]

All FETs that I have come across have have this layout:

[Drain]

[Source] [Gate]


I have looked into using BJTs but still have the same problem.

Ie all BJTs have this structure:

[Collector]
[base] [emmiter]


What i need:

[emmiter]

[base] [collector]


If anyone can tell me of a switch from rs or farnell that has this marking i'd
really appreciate it.

Been searching for ages and can't find one.

That should have been:

[D]

[G]

i did that a few years ago... it was an expensive education : )

I ended up doing a redesign... but used a TO-92 package (a bit dodgy) to
continue with the prototyping.

good luck... let us know if you find anything - could be useful one day.

I think that you will find that the way the die is manufactured will make it
virtually impossible to find what you are after.
