Pinout of 2SA1869
Here is an image showing the pin diagram of this transistor.
Classification of hFE
The 2SA1869 transistor can have a current gain of 70 to 240. The gain of the 2SA1869O will be in the range from 70 to 140, for the 2SA1869Y it will be in the range from 120 to 240.
Marking
Sometimes the "2S" prefix is not marked on the package - the 2SA1869 might only be marked "A1869".
Complementary NPN transistor
The complementary NPN transistor to the 2SA1869 is the 2SC4935.
SMD Version of 2SA1869 transistor
The 2DA1213 (SOT-89) and 2SA1213 (SOT-89) is the SMD version of the 2SA1869 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.
