Here is an image showing the pin diagram of this transistor.The 2SD1207-T transistor can have a current gain of 200 to 400. 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-S it will be in the range from 140 to 280, 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-T might only be marked "D1207-T".The complementary PNP transistor to the 2SD1207-T is the 2SB892-T.The 2SD1615 (SOT-89), 2SD1615-GL (SOT-89), 2SD1622 (SOT-89), 2SD1622-T (SOT-89), 2SD1623 (SOT-89), 2SD1623-T (SOT-89) and 2STR1160 (SOT-23) is the SMD version of the 2SD1207-T transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SD1207-T with the 2SC4408, 2SC4604, 2SC6043, 2SD1347, 2SD1347T, 2SD1835 or 2SD1835-T.
