Here is an image showing the pin diagram of this transistor.The 2SC3247-J transistor can have a current gain of 900 to 1800. The gain of the 2SC3247 will be in the range from 600 to 1800, for the 2SC3247-H it will be in the range from 600 to 1200.Sometimes the "2S" prefix is not marked on the package - the 2SC3247-J might only be marked "C3247-J".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-J transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.
