Here is an image showing the pin diagram of this transistor.The 2SA913 transistor can have a current gain of 65 to 330. The gain of the 2SA913-P will be in the range from 65 to 110, for the 2SA913-Q it will be in the range from 90 to 155, for the 2SA913-R it will be in the range from 130 to 220, for the 2SA913-S it will be in the range from 185 to 330.Sometimes the "2S" prefix is not marked on the package - the 2SA913 might only be marked "A913".The complementary NPN transistor to the 2SA913 is the 2SC1913.You can replace the 2SA913 with the 2SA1667, 2SA1668, 2SA913A, 2SB547, MJE15031, MJE15031G, MJE15033, MJE15033G, MJE5850, MJE5850G, MJF15031 or MJF15031G.
