Here is an image showing the pin diagram of this transistor.The 2SA1471-S transistor can have a current gain of 140 to 280. The gain of the 2SA1471 will be in the range from 70 to 280, for the 2SA1471-Q it will be in the range from 70 to 140, for the 2SA1471-R it will be in the range from 100 to 200.Sometimes the "2S" prefix is not marked on the package - the 2SA1471-S might only be marked "A1471-S".The complementary NPN transistor to the 2SA1471-S is the 2SC3748-S.You can replace the 2SA1471-S with the 2SA1291, 2SA1291-S, 2SA1743, 2SA1744, BD546A, BD546B, BD546C, BD808, BD810, BDT82, BDT82F, BDT84, BDT84F, BDT86, BDT86F, BDT88, BDT88F, D45H11, D45H11FP or D45H8.
