Here is an image showing the pin diagram of this transistor.The 2SC3074-Y transistor can have a current gain of 120 to 240. The gain of the 2SC3074 will be in the range from 70 to 240, for the 2SC3074-O it will be in the range from 70 to 140.Sometimes the "2S" prefix is not marked on the package - the 2SC3074-Y might only be marked "C3074-Y".The complementary PNP transistor to the 2SC3074-Y is the 2SA1244-Y.The 2SD1624 (SOT-89) and BDP949 (SOT-223) is the SMD version of the 2SC3074-Y transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC3074-Y with the 2SC3303, 2SC3303-Y, 2SD1256, 2SD1257, 2SD1257A, KTC2022D or KTC2022D-GR.
