Hello anyone please describe its features?
i gone through Data sheets but couldnt find the proper working? why it is used and how it is useful for 7 segment displays?
regards

Read the data sheet you pea-brain !
it's used as a high side switch, google "transitor switch" .

It's a general purpose, medium to low voltage, low power, pnp transistor for heaven's sake ! Aside from its respectable (but commonplace these days) noise performance and good hFE, it is wholly unremarkable.

There's nothing forcing you to answer questions in this forum, so to grudgingly answer questions in such a gruff, insulting and condescending manner is completely uncalled for.
If someone in your past treated you so thoughtlessly I apologize, but break the cycle.
Actions and attitudes like yours are what keeps many from entering technology-related hobbies. Way to screw the future, pal!

(a) It's not a forum !
(b) Where the heck are you posting from anyway ? I'll wager it's not s.e.d
It most certainly is in a design 'forum' as you like to call it.
No. Idiots who can't read the data sheet and understand it simply have no future. A modicum of simple mental competence is required to be a designer.
The question would conceivably have suited sci.electronics.basics however. FYI the Fairchild data sheet says......
Switching and Amplifier (transistor) ? High Voltage: BC556, VCEO= -65V ? Low Noise: BC559, BC560 ? Complement to BC546 ... BC 550
It's virtually (it is) a generic small signal device.
