Pinout of 2SC3540
Here is an image showing the pin diagram of this transistor.
Classification of hFE
The 2SC3540 transistor can have a current gain of 70 to 240. The gain of the 2SC3540 will be in the range from 70 to 240, for the 2SC3540-O it will be in the range from 70 to 140, for the 2SC3540-Y it will be in the range from 120 to 240.
Marking
Sometimes the "2S" prefix is not marked on the package - the 2SC3540 might only be marked "C3540".
Complementary PNP transistor
The complementary PNP transistor to the 2SC3540 is the 2SA1388.
SMD Version of 2SC3540 transistor
The BDP951 (SOT-223) and BDP953 (SOT-223) is the SMD version of the 2SC3540 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.
