Here is an image showing the pin diagram of this transistor.The 2SA1541-E transistor can have a current gain of 100 to 200. The gain of the 2SA1541 will be in the range from 40 to 320, for the 2SA1541-C it will be in the range from 40 to 80, for the 2SA1541-D it will be in the range from 60 to 120, for the 2SA1541-F it will be in the range from 160 to 320.Sometimes the "2S" prefix is not marked on the package - the 2SA1541-E might only be marked "A1541-E".The complementary NPN transistor to the 2SA1541-E is the 2SC3956-E.You can replace the 2SA1541-E with the 2SA1156, 2SA1156K, KSA1156, KSA1156Y, KSE350, KTA1703, KTA1703-Y, MJE350 or MJE350G.
