Here is an image showing the pin diagram of this transistor.The 2SC3247 transistor can have a current gain of 600 to 1800. The gain of the 2SC3247-H will be in the range from 600 to 1200, for the 2SC3247-J it will be in the range from 900 to 1800.Sometimes the "2S" prefix is not marked on the package - the 2SC3247 might only be marked "C3247".The complementary PNP transistor to the 2SC3247 is the 2SA1287.The 2SC3912 (SOT-23), 2SC3913 (SOT-23), 2SC3914 (SOT-23), 2SC3915 (SOT-23), FMMTA05 (SOT-23), KST05 (SOT-23), MMBTA05 (SOT-23), PZTA05 (SOT-223) and SMBTA05 (SOT-23) is the SMD version of the 2SC3247 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.
