Here is an image showing the pin diagram of this transistor.The 2SD1207-S transistor can have a current gain of 140 to 280. The gain of the 2SD1207 will be in the range from 100 to 560, for the 2SD1207-R it will be in the range from 100 to 200, for the 2SD1207-T it will be in the range from 200 to 400, for the 2SD1207-U it will be in the range from 280 to 560.Sometimes the "2S" prefix is not marked on the package - the 2SD1207-S might only be marked "D1207-S".The complementary PNP transistor to the 2SD1207-S is the 2SB892-S.The 2SC3444 (SOT-89), 2SD1615 (SOT-89), 2SD1615-GM (SOT-89), 2SD1622 (SOT-89), 2SD1622-S (SOT-89), 2SD1623 (SOT-89), 2SD1623-S (SOT-89), 2SD874A (SOT-89), BSP41 (SOT-223) and BSR41 (SOT-89) is the SMD version of the 2SD1207-S transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SD1207-S with the 2SC4408, 2SC4604, 2SD1347, 2SD1347S, 2SD1835 or 2SD1835-S.
