Here is an image showing the pin diagram of this transistor.The 2SC4208A transistor can have a current gain of 80 to 340. The gain of the 2SC4208A-Q will be in the range from 80 to 170, for the 2SC4208A-R it will be in the range from 120 to 240, for the 2SC4208A-S it will be in the range from 170 to 340.Sometimes the "2S" prefix is not marked on the package - the 2SC4208A might only be marked "C4208A".The complementary PNP transistor to the 2SC4208A is the 2SA1619A.The FMMTA05 (SOT-23) and KST05 (SOT-23) is the SMD version of the 2SC4208A transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC4208A with the 2SC3916, 2SC3917, 2SC3918, 2SC3919, 2SC3920, 2SC3921, 2SC3922, 2SC3923, 2SD438 or KSC1008C.
