Here is an image showing the pin diagram of this transistor.The 2SD1609-B transistor can have a current gain of 60 to 120. The gain of the 2SD1609 will be in the range from 60 to 320, for the 2SD1609-C it will be in the range from 100 to 200, for the 2SD1609-D it will be in the range from 160 to 320.Sometimes the "2S" prefix is not marked on the package - the 2SD1609-B might only be marked "D1609-B".The complementary PNP transistor to the 2SD1609-B is the 2SB1109-B.The HSD1609S-B is the TO-92 version of the 2SD1609-B.You can replace the 2SD1609-B with the 2N5655, 2N5655G, 2N5656, 2N5656G, 2SC2258, 2SC2688, 2SC2688-M, 2SC2690A, 2SC2690A-R, 2SC3416, 2SC3416-D, 2SC3417, 2SC3417-D, 2SC3502, 2SC3502-D, 2SC3503, 2SC3503-D, 2SC3600, 2SC3600-D, 2SC3601, 2SC3601-D, 2SC3788, 2SC3788-D, 2SC3789, 2SC3789-D, 2SC3790, 2SC3790-D, 2SC3955, 2SC3955-D, 2SC3956, 2SC3956-D, 2SC4212, 2SD1610, 2SD1610-B, 2SD669A, 2SD669A-B, BD127, BD128, BD157, BD158, HSD1609, HSD1609-B, KSC2258, KSC2258A, KSC2688, KSC2688-O, KSC2690A, KSC2690A-R, KSC3502, KSC3502-D, KSC3503, KSC3503-D, KSE340, MJE340, MJE340G, MJE344, MJE3440 or MJE344G.
