Pinout of 2SC2277B
The 2SC2277B 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 emitter, collector, and base leads. Here is an image showing the pin diagram of this transistor.
Classification of hFE
The 2SC2277B transistor can have a current gain of 60 to 120. The gain of the 2SC2277 will be in the range from 60 to 320, for the 2SC2277C it will be in the range from 100 to 200, for the 2SC2277D it will be in the range from 160 to 320.
Marking
Sometimes the "2S" prefix is not marked on the package - the 2SC2277B might only be marked "C2277B".
Complementary PNP transistor
The complementary PNP transistor to the 2SC2277B is the 2SA993B.
