Here is an image showing the pin diagram of this transistor.The 2SD601A-S transistor can have a current gain of 290 to 460. The gain of the 2SD601A will be in the range from 160 to 460, for the 2SD601A-Q it will be in the range from 160 to 260, for the 2SD601A-R it will be in the range from 210 to 340.Sometimes the "2S" prefix is not marked on the package - the 2SD601A-S might only be marked "D601A-S".The complementary PNP transistor to the 2SD601A-S is the 2SB709A-S.You can replace the 2SD601A-S with the 2SC1623, 2SC2412, 2SC2412-S, 2SC2712, 2SC3441, 2SC3441-F, 2SC3912, 2SC3913, 2SC3914, 2SC3915, 2SC4738, 2STR1160, BC846, FMMT619, FMMT620, FMMTA05, FMMTA06, KSC1623, KST05, KST06, KTC3875, KTC3875S, MMBT2484, MMBT5210, MMBT6428, MMBTA05, MMBTA06, PMBT6428, PMBTA06, SMBTA05 or SMBTA06.
