The BC328-40 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 BC328-40 transistor can have a current gain of 250 to 630. The gain of the BC328 will be in the range from 100 to 630, for the BC328-16 it will be in the range from 100 to 250, for the BC328-25 it will be in the range from 160 to 400.The complementary NPN transistor to the BC328-40 is the BC338-40.The BC808 (SOT-23), BC808-40 (SOT-23), BC808-40W (SOT-323) and BC808W (SOT-323) is the SMD version of the BC328-40 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the BC328-40 with the BC327 or BC327-40.
