Here is an image showing the pin diagram of this transistor.The 2SC3939-R transistor can have a current gain of 130 to 220. The gain of the 2SC3939 will be in the range from 130 to 330, for the 2SC3939-S it will be in the range from 185 to 330.Sometimes the "2S" prefix is not marked on the package - the 2SC3939-R might only be marked "C3939-R".The complementary PNP transistor to the 2SC3939-R is the 2SA1533-R.The 2SC2882 (SOT-89), 2SC2882-Y (SOT-89), 2SC3438 (SOT-89), 2SC4209 (SOT-23), 2SC4209-Y (SOT-23), FMMTA06 (SOT-23), KST06 (SOT-23), KTC4374 (SOT-89), KTC4374Y (SOT-89), MMBTA06 (SOT-23), PMBTA06 (SOT-23), PZTA06 (SOT-223) and SMBTA06 (SOT-23) is the SMD version of the 2SC3939-R transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC3939-R with the 2N5551C, 2SC1509, 2SC1509-R, 2SC2235, 2SC2235-Y, 2SC2274K, 2SC2383, 2SC3228, 2SC3244, 2SC3328, 2SC3328-Y, 2SC3332, 2SC3708, 2SD1211, 2SD1211-R, 2SD438, 2SD667, KSC1009C, KSC1009CY, KSC2316, KSC2316Y, KSC2383, KSP8099C, KTC1006, KTC1027, KTC1027-O, KTC1027-Y or KTC3228.
