Pinout of 2SA913A
Here is an image showing the pin diagram of this transistor.
Classification of hFE
The 2SA913A transistor can have a current gain of 65 to 330. The gain of the 2SA913A-P will be in the range from 65 to 110, for the 2SA913A-Q it will be in the range from 90 to 155, for the 2SA913A-R it will be in the range from 130 to 220, for the 2SA913A-S it will be in the range from 185 to 330.
Marking
Sometimes the "2S" prefix is not marked on the package - the 2SA913A might only be marked "A913A".
Complementary NPN transistor
The complementary NPN transistor to the 2SA913A is the 2SC1913A.
SMD Version of 2SA913A transistor
The KST93 (SOT-23) is the SMD version of the 2SA913A transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.
