Here is an image showing the pin diagram of this transistor.The 2SC3244-D transistor can have a current gain of 90 to 180. The gain of the 2SC3244 will be in the range from 55 to 300, for the 2SC3244-C it will be in the range from 55 to 110, for the 2SC3244-E it will be in the range from 150 to 300.Sometimes the "2S" prefix is not marked on the package - the 2SC3244-D might only be marked "C3244-D".The complementary PNP transistor to the 2SC3244-D is the 2SA1284-D.The 2SC3438 (SOT-89) and 2SC3438-D (SOT-89) is the SMD version of the 2SC3244-D transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC3244-D with the 2N5551C, 2SC2235, 2SC2383, 2SC3228, 2SD667A, KSC1009C, KSC2316, KSC2383, KTC1027, KTC1027-O, KTC1027-Y or KTC3228.
