The 2SD1513-U 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.The 2SD1513-U transistor can have a current gain of 300 to 650. The gain of the 2SD1513 will be in the range from 135 to 650, for the 2SD1513-K it will be in the range from 200 to 400, for the 2SD1513-L it will be in the range from 135 to 270.Sometimes the "2S" prefix is not marked on the package - the 2SD1513-U might only be marked "D1513-U".The complementary PNP transistor to the 2SD1513-U is the 2SB1068-U.The 2SC3443 (SOT-89) is the SMD version of the 2SD1513-U transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SD1513-U with the 2SC3242, 2SC3242A, 2SC3266 or KTD1146.
