Here is an image showing the pin diagram of this transistor.The 2SA1371-C transistor can have a current gain of 40 to 80. The gain of the 2SA1371 will be in the range from 40 to 320, for the 2SA1371-D it will be in the range from 60 to 120, for the 2SA1371-E it will be in the range from 100 to 200, for the 2SA1371-F it will be in the range from 160 to 320.Sometimes the "2S" prefix is not marked on the package - the 2SA1371-C might only be marked "A1371-C".The complementary NPN transistor to the 2SA1371-C is the 2SC3468-C.The 2SA1721 (SOT-23), 2SA1721-R (SOT-23) and PMBTA92 (SOT-23) is the SMD version of the 2SA1371-C transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA1371-C with the 2SA1091, 2SA1091-R, 2SA1625, 2SA1625-M, KSA1625, KSA1625-M or KTA1279.
