For example Diodes/Zetex, navigate a bit the site and you'll find at: http://www.diodes.com/products/catalog/list.php?parent-id=28 that they are: "Built with adjacent die from a single wafer: DC Current Gain, hFE, VCE(sat), VBE(sat) are matched to a 2% maximum tolerance."
Hey, sweet; I didn't know about those! Thanks for the pointer. That does make surface mount a win for my application.
Anybody know of any other sources of surface mount transistor pairs on the same die?
(I'm still going to need to hand-match some JFETs because I'm using them in an unusual configuration. And I'll probably need TO-92 footprints for those, but I'll look into it some more. )
