Re: gEDA-user: sot-23 pin numbers


My recollection is that pins (1) an (2) are on the same side of the package.  Number CCW when viewed from top.  As DJ said, this seems to be consistent for BJT and FET parts.  Diodes are another matter - when the part contains a pair all arrangements are possible :).

Based on my limited experience, I've found that the control (base,
gate), power (emitter, source) and output (collector, drain) are
always on the same pins on sot-shaped devices, regardless of fet/bjt
or p/n.  The spec sheets always seem to number those pins the same
too, but that doesn't mean that gschem/pcb does.
