The 2SC2544-E 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 2SC2544-E transistor can have a current gain of 400 to 800. The gain of the 2SC2544 will be in the range from 250 to 1200, for the 2SC2544-D it will be in the range from 250 to 500.Sometimes the "2S" prefix is not marked on the package - the 2SC2544-E might only be marked "C2544-E".The complementary PNP transistor to the 2SC2544-E is the 2SA1082-E.The 2SC1622A (SOT-23), FJV1845 (SOT-23) and FJV1845-E (SOT-23) is the SMD version of the 2SC2544-E transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC2544-E with the 2SC2547, 2SC2547-E, 2SC3245, 2SC3245-G or 2SC3245A.
