Here is an image showing the pin diagram of this transistor.The 2SD1615-GM transistor can have a current gain of 135 to 270. The gain of the 2SD1615 will be in the range from 135 to 600, for the 2SD1615-GK it will be in the range from 300 to 600, for the 2SD1615-GL it will be in the range from 200 to 400.Sometimes the "2S" prefix is not marked on the package - the 2SD1615-GM might only be marked "D1615-GM".The complementary PNP transistor to the 2SD1615-GM is the 2SB1115-YM.You can replace the 2SD1615-GM with the 2SC3444, 2SD1615A, 2SD1615A-GQ, 2SD1622, 2SD1623, 2SD1624, 2SD874A, BSR41, BSR43 or KTC4378.
