Pinout of 2SA816
Here is an image showing the pin diagram of this transistor.
Classification of hFE
The 2SA816 transistor can have a current gain of 70 to 240. The gain of the 2SA816-O will be in the range from 70 to 140, for the 2SA816-Y it will be in the range from 120 to 240.
Marking
Sometimes the "2S" prefix is not marked on the package - the 2SA816 might only be marked "A816".
Complementary NPN transistor
The complementary NPN transistor to the 2SA816 is the 2SC1626.
SMD Version of 2SA816 transistor
The 2SA1368 (SOT-89), FMMTA56 (SOT-23), KST56 (SOT-23) and KTA1662 (SOT-89) is the SMD version of the 2SA816 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.
