[SOLVED] BJT complementory pairs

[myfaithnka]

hi all,

i am trying to make a fading led circuit for Easter, please suggest me a low power equavalent pair (npn-pnp)

I have bjts like bc548,bc547,bc 107 available here.

sl100 and sk100 is not required here i assume (10 leds, 12 V VCC ).

can some one share a link explaining the complementary pairs for this transistors ?


thanks in advance.

There's a nice list of low power NPN transistors and their PNP complements here: https://users.tpg.com.au/gerskine/greg/PNP%20Small%20Signal%20Transistors.htm
