The KSC815R 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 KSC815CR transistor (with suffix "C") is the center collector version of the KSC815R.
Here is an image showing the pin diagram of this transistor.The KSC815R transistor can have a current gain of 40 to 80. 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 KSC815O it will be in the range from 70 to 140, for the KSC815Y it will be in the range from 120 to 240.The complementary PNP transistor to the KSC815R is the KSA539R.The 2SC3803 (SOT-89) and 2SC3803-R (SOT-89) is the SMD version of the KSC815R transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.The 2SC815R is the TO-92 version of the KSC815R.You can replace the KSC815R with the 2SC1008, 2SC1008R, 2SC815, 2SC815R, BC537, BC537-6, BC538, BC538-6, KSC1008, KSC1008R, PN3568 or ZTX452.
