The 2SC1209-C 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, base, and collector leads.
Here is an image showing the pin diagram of this transistor.The 2SC1209-C transistor can have a current gain of 55 to 110. The gain of the 2SC1209 will be in the range from 55 to 300, for the 2SC1209-D it will be in the range from 90 to 180, for the 2SC1209-E it will be in the range from 150 to 300.Sometimes the "2S" prefix is not marked on the package - the 2SC1209-C might only be marked "C1209-C".The complementary PNP transistor to the 2SC1209-C is the 2SA695-C.You can replace the 2SC1209-C with the MPS3705, MPS3706, MPS6601, MPS6601G, MPS6602, MPS6602G, PN2218, PN2218A, PN2221 or PN2221A.
