The KSC815CY 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, collector, and base leads. Suffix "C" means center collector in KSC815Y.
Here is an image showing the pin diagram of this transistor.The KSC815CY transistor can have a current gain of 120 to 240. The gain of the KSC815C will be in the range from 40 to 400, for the KSC815CG it will be in the range from 200 to 400, for the KSC815CO it will be in the range from 70 to 140, for the KSC815CR it will be in the range from 40 to 80.The complementary PNP transistor to the KSC815CY is the KSA539CY.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 KSC815CY transistor.
