Here is an image showing the pin diagram of this transistor.The 2SC3853-Y transistor can have a current gain of 90 to 180. The gain of the 2SC3853 will be in the range from 50 to 180, for the 2SC3853-O it will be in the range from 50 to 100, for the 2SC3853-P it will be in the range from 70 to 140.Sometimes the "2S" prefix is not marked on the package - the 2SC3853-Y might only be marked "C3853-Y".The complementary PNP transistor to the 2SC3853-Y is the 2SA1489-Y.The BDP953 (SOT-223) is the SMD version of the 2SC3853-Y transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC3853-Y with the 2SC2563, 2SC2577, 2SC2578, 2SC2579, 2SC2580, 2SC2581, 2SC2706, 2SC2837, 2SC2837-Y, 2SC3284, 2SC3284-Y, 2SC3519, 2SC3519-Y, 2SC3835, 2SC3854, 2SC3854-Y, 2SC3855, 2SC3855-Y, 2SC4278, 2SC4466, 2SC4466-Y, 2SC4467, 2SC4467-Y, 2SC4468, 2SC4468-Y, 2SC4652, 2SD1046, 2SD1047, 2SD1288, 2SD1289, 2SD1717, 2SD2052, 2SD2053, 2SD731, 2SD843, 2SD895, BD245B, BD245C, BD249B, BD249C, BDV93, BDV95, FJA4310, FJA4310Y, KTD1047, KTD1047B or TIP35CA.
