    All,

    I've searched on google and on this forum and haven't found any info in regards to sot-23 package and the 2n4403 and 2n4401 bjt's. In the datasheets for these parts.

    http://www.fairchildsemi.com/ds/2N/2N4403.pdf
    http://www.fairchildsemi.com/ds/2N/2N4401.pdf

    They don't say the pinout for them meaning what pin number goes to either the base, emitter, or collector. Is there a standard for bjt transistors in a sot-23 package? It really would be nice if the datasheet just had the pin numbers there to avoid confusion. I'm assuming there must be a standard?

    Thanks

    -mike

    Thanks for the info. Some great "decoders" there. So, I'm assuming there is a standard pinout for a sot-23 package? I didn't see pin numbers in the sheets above.

    I think I found it. Does everyone agree with this representation of the sot-23 package in regards to pinout?

    Mike,

    If you open the datasheets that you linked to, you will find that on the very first page, a picture of the sot-23 package with the pins marked on it.
