Here is an image showing the pin diagram of this transistor.The 2SA1294 transistor can have a current gain of 50 to 140. The gain of the 2SA1294 will be in the range from 50 to 140, for the 2SA1294-O it will be in the range from 50 to 100, for the 2SA1294-Y it will be in the range from 70 to 140.Sometimes the "2S" prefix is not marked on the package - the 2SA1294 might only be marked "A1294".The complementary NPN transistor to the 2SA1294 is the 2SC3263.You can replace the 2SA1294 with the 2SA2151A, 2SA2151A-O, 2SA2151A-P, 2SA2151A-Y, 2SA2223, 2SA2223A, MAG9413, MJW1302A or MJW1302AG.
