The 2SC2546-F 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.The 2SC2546-F transistor can have a current gain of 600 to 1200. The gain of the 2SC2546 will be in the range from 250 to 1200, for the 2SC2546-D it will be in the range from 250 to 500, for the 2SC2546-E it will be in the range from 400 to 800.Sometimes the "2S" prefix is not marked on the package - the 2SC2546-F might only be marked "C2546-F".You can replace the 2SC2546-F with the 2SC2543, 2SC2543-F or 2SC2544.
