Here is an image showing the pin diagram of this transistor.The 2SC3243-D transistor can have a current gain of 90 to 180. The gain of the 2SC3243 will be in the range from 55 to 300, for the 2SC3243-C it will be in the range from 55 to 110, for the 2SC3243-E it will be in the range from 150 to 300.Sometimes the "2S" prefix is not marked on the package - the 2SC3243-D might only be marked "C3243-D".The complementary PNP transistor to the 2SC3243-D is the 2SA1283-D.The 2SC3444 (SOT-89), 2SC3444-D (SOT-89), BCP55 (SOT-223), BCX55 (SOT-89), FMMTA05 (SOT-23) and KST05 (SOT-23) is the SMD version of the 2SC3243-D transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC3243-D with the 2SC3328, 2SD667 or 2SD667A.
