Here is an image showing the pin diagram of this transistor.The 2SC3855-Y transistor can have a current gain of 90 to 180. The gain of the 2SC3855 will be in the range from 50 to 180, for the 2SC3855-O it will be in the range from 50 to 100, for the 2SC3855-P it will be in the range from 70 to 140.Sometimes the "2S" prefix is not marked on the package - the 2SC3855-Y might only be marked "C3855-Y".The complementary PNP transistor to the 2SC3855-Y is the 2SA1491-Y.You can replace the 2SC3855-Y with the 2SC2581, 2SC2706, 2SC2837, 2SC2837-Y, 2SC3284, 2SC3284-Y, 2SC3519, 2SC3519-Y, 2SC3519A, 2SC3519A-O, 2SC3519A-P, 2SC3519A-Y, 2SC3856, 2SC3856-Y, 2SC3907, 2SC3907-O, 2SC4278, 2SC4468, 2SC4468-Y, 2SC6011, 2SC6011-Y, 2SC6011A, 2SC6011A-O, 2SC6011A-P, 2SC6011A-Y, 2SD1047, 2SD1717, 2SD1718, FJA4310, FJA4310Y, KTD1047, KTD1047B, MJW3281A or MJW3281AG.
