Here is an image showing the pin diagram of this transistor.The 2SD600-E transistor can have a current gain of 100 to 200. The gain of the 2SD600 will be in the range from 60 to 320, for the 2SD600-D it will be in the range from 60 to 120, for the 2SD600-F it will be in the range from 160 to 320.Sometimes the "2S" prefix is not marked on the package - the 2SD600-E might only be marked "D600-E".The complementary PNP transistor to the 2SD600-E is the 2SB631-E.The 2SC2881 (SOT-89), 2SC3438 (SOT-89), 2SC3438-D (SOT-89), FMMT624 (SOT-23) and KTC4373 (SOT-89) is the SMD version of the 2SD600-E transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SD600-E with the 2SC1565, 2SC1565A, 2SC2481, 2SC2481-O, 2SC2690, 2SC2690-Q, 2SC2690A, 2SC2690A-Q, 2SC2824, 2SC3117, 2SC3117-R, 2SC3421, 2SC3621, 2SC3621-O, 2SC3902, 2SC3902-R, 2SD1684, 2SD1684-Q, 2SD1724, 2SD1724-R, 2SD1725, 2SD1725-R, 2SD600K, 2SD600K-E, 2SD669, 2SD669-C, 2SD669A, 2SD669A-C, BD791, KSC2690, KSC2690-O, KSC2690A, KSC2690A-O, KTC2800, KTC2803, KTC2803-Y or MJE244.
