The BC448B 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 NPN transistor to the BC448B is the BC447B.You can replace the BC448B with the BC448, BC450 or BC450B.
