Pinout of C1815
The C1815 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. Here is an image showing the pin diagram of this transistor.
Classification of hFE
The C1815 transistor can have a current gain of 70 to 700. The gain of the C1815BL will be in the range from 350 to 700, for the C1815GR it will be in the range from 200 to 400, for the C1815O it will be in the range from 70 to 140, for the C1815Y it will be in the range from 120 to 240.
Complementary PNP transistor
The complementary PNP transistor to the C1815 is the A1015.
