The BC490L 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 BC490L transistor can have a current gain of 60 to 150. The gain of the BC490 will be in the range from 60 to 400, for the BC490A it will be in the range from 100 to 250, for the BC490B it will be in the range from 160 to 400.The complementary NPN transistor to the BC490L is the BC489L.The 2SA1368 (SOT-89), BCP53 (SOT-223), FMMTA56 (SOT-23), KST56 (SOT-23) and MMBT4356 (SOT-23) is the SMD version of the BC490L transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.
