The BC485A is manufactured in a plastic TO-92 case. When looking at the flat side with the leads pointed downward, the three leads emerging from the transistor are, from left to right, the collector, base, and emitter leads.
Here is an image showing the pin diagram of this transistor.The BC485A transistor can have a current gain of 100 to 250. The gain of the BC485 will be in the range from 60 to 400, for the BC485B it will be in the range from 160 to 400, for the BC485L it will be in the range from 60 to 150.The complementary PNP transistor to the BC485A is the BC486A.The 2SC3325 (SOT-23), 2SC3912 (SOT-23), 2SC3913 (SOT-23), 2SC3914 (SOT-23), 2SC3915 (SOT-23), BC817 (SOT-23), BC817-16 (SOT-23), BC817-16W (SOT-323), BC817W (SOT-323), BCP54 (SOT-223), BCP54-16 (SOT-223), BCX19 (SOT-23), BCX54 (SOT-89) and BCX54-16 (SOT-89) is the SMD version of the BC485A transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the BC485A with the BC487, BC487A, BC489 or BC489A.
