Here is an image showing the pin diagram of this transistor.The 2SA1315 transistor can have a current gain of 70 to 240. The gain of the 2SA1315-O will be in the range from 70 to 140, for the 2SA1315-Y it will be in the range from 120 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SA1315 might only be marked "A1315".The complementary NPN transistor to the 2SA1315 is the 2SC3328.The BCP53 (SOT-223) and BCX53 (SOT-89) is the SMD version of the 2SA1315 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.
