The KSC815CR 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 KSC815R.
Here is an image showing the pin diagram of this transistor.The KSC815CR transistor can have a current gain of 40 to 80. 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 KSC815CY it will be in the range from 120 to 240.The complementary PNP transistor to the KSC815CR is the KSA539CR.The 2SC3803 (SOT-89) and 2SC3803-R (SOT-89) is the SMD version of the KSC815CR transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KSC815CR with the 2SC2000, 2SC2000-M, BC635, BC637, BC639, KSC1008C, KSC1008CR, KSC2331, KSC2331R or PN3642.
