Here is an image showing the pin diagram of this transistor.The 2SC1565A transistor can have a current gain of 65 to 330. The gain of the 2SC1565A-P will be in the range from 65 to 110, for the 2SC1565A-Q it will be in the range from 90 to 155, for the 2SC1565A-R it will be in the range from 130 to 220, for the 2SC1565A-S it will be in the range from 185 to 330.Sometimes the "2S" prefix is not marked on the package - the 2SC1565A might only be marked "C1565A".The complementary PNP transistor to the 2SC1565A is the 2SA795A.The KST43 (SOT-23) is the SMD version of the 2SC1565A transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.
