The 2SA1481-E is manufactured in a plastic TO-92 case. When looking at the flat side with the leads pointed downward, the three leads emerging from the transistor are, from left to right, the emitter, collector, and base leads.
Here is an image showing the pin diagram of this transistor.The 2SA1481-E transistor can have a current gain of 100 to 200. The gain of the 2SA1481 will be in the range from 100 to 560, for the 2SA1481-F it will be in the range from 160 to 320, for the 2SA1481-G it will be in the range from 280 to 560.Sometimes the "2S" prefix is not marked on the package - the 2SA1481-E might only be marked "A1481-E".The complementary NPN transistor to the 2SA1481-E is the 2SC2960-E.The 2SA812 (SOT-23), 2SA812-M4 (SOT-23), FJX733 (SOT-323), KSA812 (SOT-23) and KSA812-O (SOT-23) is the SMD version of the 2SA1481-E transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA1481-E with the 2SA1015, 2SA1020, 2SA1048, 2SA1246, 2SA1246-R, 2SA1266, 2SA1267, 2SA1283, 2SA1284, 2SA1315, 2SA1317, 2SA1317-R, 2SA1318, 2SA1318-R, 2SA1391, 2SA1391-R, 2SA1392, 2SA1392-R, 2SA1450, 2SA1450-R, 2SA1522, 2SA1523, 2SA1524, 2SA1525, 2SA1526, 2SA1527, 2SA1528, 2SA1529, 2SA1533, 2SA1534A, 2SA1619A, 2SA200, 2SA684, 2SA720, 2SA777, 2SA817, 2SA817A, 2SA935, 2SA953, 2SA954, 2SA984, 2SA984-E, 2SA984K, 2SA984K-E, 2SA993, 2SA993C, 2SB1229, 2SB1229-R, 2SB560, 2SB560-E, 2SB647, 2SB647A, 2SB647AC, 2SB647C, 2SB740, 2SB740-B, 2SB764, 2SB764-E, 2SB892, 2SB892-R, 2SB985, 2SB985R, A1015, A733, BC212, BC212A, H733, KSA1015, KSA708C, KSA733C, KSA931, KSP2907AC, KSP8598C, KSP8599C, KTA1266, KTA1267, KTA1274, KTA1281, KTA200, KTA708, KTA708-Y, KTB764, KTB764-Y or PN3645.
