The KSC815O 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. The KSC815CO transistor (with suffix "C") is the center collector version of the KSC815O.
Here is an image showing the pin diagram of this transistor.The KSC815O transistor can have a current gain of 70 to 140. The gain of the KSC815 will be in the range from 40 to 400, for the KSC815G it will be in the range from 200 to 400, for the KSC815R it will be in the range from 40 to 80, for the KSC815Y it will be in the range from 120 to 240.The complementary PNP transistor to the KSC815O is the KSA539O.The 2SC2712 (SOT-23), 2SC2712-O (SOT-23), 2SC3803 (SOT-89), 2SC3803-O (SOT-89), 2SC4116 (SOT-323), 2SC4116-O (SOT-323), 2SC4738 (SOT-23), 2SC4738-O (SOT-23), FJX945 (SOT-323), FJX945O (SOT-323), KTC3875 (SOT-23), KTC3875O (SOT-23), KTC3875S (SOT-23) and KTC3875S-O (SOT-23) is the SMD version of the KSC815O transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.The 2SC815O is the TO-92 version of the KSC815O.You can replace the KSC815O with the 2SC1008, 2SC1008O, 2SC1211, 2SC815, 2SC815O, BC537, BC537-10, BC538, BC538-10, KSC1008, KSC1008O, KSP05, KSP06, KTC815, KTC815-O, KTC815-Y, MPS6717, MPS6717G, MPSW05, MPSW05G, MPSW06, MPSW06G, ZTX451 or ZTX452.
