The 2SC815R 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 2SC815R transistor can have a current gain of 40 to 80. The gain of the 2SC815 will be in the range from 40 to 400, for the 2SC815G it will be in the range from 200 to 400, for the 2SC815O it will be in the range from 70 to 140, for the 2SC815Y it will be in the range from 120 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SC815R might only be marked "C815R".The complementary PNP transistor to the 2SC815R is the 2SA539R.The 2SC3803 (SOT-89) and 2SC3803-R (SOT-89) is the SMD version of the 2SC815R transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.The KSC815R is the TO-92 version of the 2SC815R.You can replace the 2SC815R with the 2SC1008, 2SC1008R, BC537, BC537-6, BC538, BC538-6, KSC1008, KSC1008R, KSC815, KSC815R, PN3568 or ZTX452.
