Hello Electronic Circuits Help Forum,
With the flat facet of the TO-92 package facing you
and the three legs pointing down the transistor in the data sheet
http://www.nxp.com/documents/data_sheet/PN2222A.pdf
marked PN2222A has the collector on the left
the base in the middle and the emitter on the right.
With the flat facet of the TO-92 package facing you

https://www.fairchildsemi.com/datasheets/PN/PN2222A.pdf
marked PN2222A has the collector on the right
the base in the middle and the emitter on the left.
So do different manufacturers have different pinouts for
a transistor with the same name?
Is the base always in the middle?
Without the datasheet is there a way of knowing which
pin has which function?
Thanks.
