Here is an image showing the pin diagram of this transistor.The 2SD1609-D transistor can have a current gain of 160 to 320. The gain of the 2SD1609 will be in the range from 60 to 320, for the 2SD1609-B it will be in the range from 60 to 120, for the 2SD1609-C it will be in the range from 100 to 200.Sometimes the "2S" prefix is not marked on the package - the 2SD1609-D might only be marked "D1609-D".The complementary PNP transistor to the 2SD1609-D is the 2SB1109-D.The HSD1609S-D is the TO-92 version of the 2SD1609-D.You can replace the 2SD1609-D with the 2SC1565A, 2SC2258, 2SC2682, 2SC2682P, 2SC2690A, 2SC2690A-P, 2SC2911, 2SC2912, 2SC3116, 2SC3117, 2SC3416, 2SC3416-F, 2SC3417, 2SC3417-F, 2SC3502, 2SC3502-F, 2SC3503, 2SC3503-F, 2SC3600, 2SC3600-F, 2SC3601, 2SC3601-F, 2SC3787, 2SC3788, 2SC3788-F, 2SC3789, 2SC3789-F, 2SC3790, 2SC3790-F, 2SC3902, 2SC3955, 2SC3955-F, 2SC3956, 2SC3956-F, 2SD1610, 2SD1610-D, BD127, BD128, HSD1609, HSD1609-D, KSC2258, KSC2258A, KSC2682, KSC2682Y, KSC2690A, KSC2690A-Y, KSC3502, KSC3502-F, KSC3503 or KSC3503-F.
