The S9015B 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 S9015B transistor can have a current gain of 100 to 300. The gain of the S9015 will be in the range from 60 to 1000, for the S9015A it will be in the range from 60 to 150, for the S9015C it will be in the range from 200 to 600, for the S9015D it will be in the range from 400 to 1000.The complementary NPN transistor to the S9015B is the S9014B.The 2SA812 (SOT-23) and KSA812 (SOT-23) is the SMD version of the S9015B transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the S9015B with the 2SA697, 2SA708, BC527, BC528, HS733, KN2907A, KSA708, KSA733, KSP2907A, KSP55, KSP56, KSP8598, KSP8599, KTC9015, KTC9015B, KTN2907A, MPS2907A, MPS2907AG, MPS4354, MPS4355, MPS751, MPS751G, MPS8598, MPS8598G, MPS8599, MPS8599G, MPSA55, MPSA55G, MPSA56, MPSA56G, MPSW55, MPSW55G, MPSW56, MPSW56G, P2N2907A, P2N2907AG, PN200, PN2905A, PN2907A, PN4354, PN4355, SS9015, SS9015B, ZTX550 or ZTX951.
