The 2SC815Y 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 2SC815Y transistor can have a current gain of 120 to 240. 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 2SC815R it will be in the range from 40 to 80.Sometimes the "2S" prefix is not marked on the package - the 2SC815Y might only be marked "C815Y".The complementary PNP transistor to the 2SC815Y is the 2SA539Y.The 2SC1623 (SOT-23), 2SC2412 (SOT-23), 2SC2412-Q (SOT-23), 2SC2712 (SOT-23), 2SC2712-Y (SOT-23), 2SC3803 (SOT-89), 2SC3803-Y (SOT-89), 2SC4116 (SOT-323), 2SC4116-Y (SOT-323), 2SC4738 (SOT-23), 2SC4738-Y (SOT-23), FJX945 (SOT-323), FJX945Y (SOT-323), KSC1623 (SOT-23), KTC3875 (SOT-23), KTC3875S (SOT-23), KTC3875S-Y (SOT-23), KTC3875Y (SOT-23) and TMBT3904 (SOT-23) is the SMD version of the 2SC815Y transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.The KSC815Y, KTC815-Y is the TO-92 version of the 2SC815Y.You can replace the 2SC815Y with the 2SC1008, 2SC1008Y, 2SC1211, BC537, BC537-16, BC538, BC538-16, KSC1008, KSC1008Y, KSC815, KSC815Y, KSP05, KSP06, KSP8098, KSP8099, KTC815, KTC815-O, KTC815-Y, MPS651, MPS651G, MPS6717, MPS6717G, MPS8098, MPS8098G, MPS8099, MPS8099G, MPSA05, MPSA05G, MPSA06, MPSA06G, MPSW05, MPSW05G, MPSW06, MPSW06G, PN100, PN4033 or ZTX450.
