The 2SC2277 is manufactured in a plastic TO-92 case. When looking at the flat side with the leads pointed downward, the three leads emerging from the transistor are, from left to right, the emitter, collector, and base leads.
Here is an image showing the pin diagram of this transistor.The 2SC2277 transistor can have a current gain of 60 to 320. The gain of the 2SC2277B will be in the range from 60 to 120, for the 2SC2277C it will be in the range from 100 to 200, for the 2SC2277D it will be in the range from 160 to 320.Sometimes the "2S" prefix is not marked on the package - the 2SC2277 might only be marked "C2277".The complementary PNP transistor to the 2SC2277 is the 2SA993.The 2SC3912 (SOT-23), 2SC3913 (SOT-23), 2SC3914 (SOT-23), 2SC3915 (SOT-23), FMMTA05 (SOT-23) and KST05 (SOT-23) is the SMD version of the 2SC2277 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC2277 with the 2SC2274, 2SC2274K, 2SC3916, 2SC3917, 2SC3918, 2SC3919, 2SC3920, 2SC3921, 2SC3922, 2SC3923, 2SD438, 2SD667, 2SD863, KSC1008C or KTD863.
