The BC445B 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 complementary PNP transistor to the BC445B is the BC446B.You can replace the BC445B with the BC445, BC447, BC447B, BC449 or BC449B.
