Here is an image showing the pin diagram of this transistor.The 2SC1565A-Q transistor can have a current gain of 90 to 155. The gain of the 2SC1565A will be in the range from 65 to 330, for the 2SC1565A-P it will be in the range from 65 to 110, 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-Q might only be marked "C1565A-Q".The complementary PNP transistor to the 2SC1565A-Q is the 2SA795A-Q.The KST43 (SOT-23) is the SMD version of the 2SC1565A-Q transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC1565A-Q with the BD410.
