Here is an image showing the pin diagram of this transistor.The 2SA1315-Y transistor can have a current gain of 120 to 240. The gain of the 2SA1315 will be in the range from 70 to 240, for the 2SA1315-O it will be in the range from 70 to 140.Sometimes the "2S" prefix is not marked on the package - the 2SA1315-Y might only be marked "A1315-Y".The complementary NPN transistor to the 2SA1315-Y is the 2SC3328-Y.The BCP53 (SOT-223), BCP53-16 (SOT-223), BCX53 (SOT-89), BCX53-16 (SOT-89), BSP33 (SOT-223) and BSR33 (SOT-89) is the SMD version of the 2SA1315-Y transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.
