The 2SC815 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 2SC815 transistor can have a current gain of 40 to 400. The gain of the 2SC815G will be in the range from 200 to 400, for the 2SC815O it will be in the range from 70 to 140, for the 2SC815R it will be in the range from 40 to 80, for the 2SC815Y it will be in the range from 120 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SC815 might only be marked "C815".The complementary PNP transistor to the 2SC815 is the 2SA539.The KSC815, KTC815 is the TO-92 version of the 2SC815.You can replace the 2SC815 with the 2SC1008, BC537, BC538, KSC1008 or KSC815.
