Here is an image showing the pin diagram of this transistor.The 2SA1287 transistor can have a current gain of 400 to 800. The gain of the 2SA1287-G will be in the range from 400 to 800.Sometimes the "2S" prefix is not marked on the package - the 2SA1287 might only be marked "A1287".The complementary NPN transistor to the 2SA1287 is the 2SC3247.The 2SA1518 (SOT-23), 2SA1519 (SOT-23), 2SA1520 (SOT-23), 2SA1521 (SOT-23), FMMTA55 (SOT-23), KST55 (SOT-23), MMBTA55 (SOT-23), PZTA55 (SOT-223) and SMBTA55 (SOT-23) is the SMD version of the 2SA1287 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.
