Pinout of BC557C
The BC557C 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.
Classification of hFE
The BC557C transistor can have a current gain of 420 to 800. The gain of the BC557 will be in the range from 110 to 800, for the BC557A it will be in the range from 110 to 220, for the BC557B it will be in the range from 200 to 450.
Complementary NPN transistor
The complementary NPN transistor to the BC557C is the BC547C.
