Here is an image showing the pin diagram of this transistor.The 2SC3284 transistor can have a current gain of 50 to 180. The gain of the 2SC3284-O will be in the range from 50 to 100, for the 2SC3284-P it will be in the range from 70 to 140, for the 2SC3284-Y it will be in the range from 90 to 180.Sometimes the "2S" prefix is not marked on the package - the 2SC3284 might only be marked "C3284".The complementary PNP transistor to the 2SC3284 is the 2SA1303.You can replace the 2SC3284 with the 2SC3519, 2SC3519A, 2SC3519A-O, 2SC3519A-P, 2SC3519A-Y, 2SC6011, 2SC6011A, 2SC6011A-O, 2SC6011A-P, 2SC6011A-Y, MJW3281A or MJW3281AG.
