The 2SA628-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 2SA628-E transistor can have a current gain of 150 to 300. The gain of the 2SA628 will be in the range from 55 to 800, for the 2SA628-C it will be in the range from 55 to 110, for the 2SA628-D it will be in the range from 90 to 180, for the 2SA628-F it will be in the range from 250 to 500, for the 2SA628-G it will be in the range from 400 to 800.Sometimes the "2S" prefix is not marked on the package - the 2SA628-E might only be marked "A628-E".The BC858 (SOT-23), BC858W (SOT-323), BC859 (SOT-23) and BC859W (SOT-323) is the SMD version of the 2SA628-E transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA628-E with the 2N3702, 2N4058, 2N4059, 2N4061, 2N4952, 2N4954, 2N5366, 2SA1015, 2SA1031, 2SA1032, 2SA1048, 2SA1150, 2SA1175, 2SA1246, 2SA1266, 2SA1267, 2SA1271, 2SA1273, 2SA1317, 2SA1318, 2SA1382, 2SA1391, 2SA1392, 2SA1481, 2SA1522, 2SA1523, 2SA1524, 2SA1525, 2SA1526, 2SA1527, 2SA1528, 2SA1529, 2SA1534, 2SA1534A, 2SA1619, 2SA1619A, 2SA1680, 2SA1761, 2SA608, 2SA683, 2SA684, 2SA719, 2SA720, 2SA733, 2SA928A, 2SA950, 2SA952, 2SA966, 2SA984, 2SA993, 2SB1116, 2SB1229, 2SB564, 2SB598, 2SB621, 2SB621A, 2SB740, 2SB764, 2SB892, 2SB985, A1015, A733, BC212, BC212A, BC257, BC258, H733, KSA1015, KSA642C, KSA733C, KSA928A, KSB1116, KSB1116S, KSB564AC, KSB810, KSB811, KTA1266, KTA1267, KTA1271, KTA1272, KTA1273, KTA1282, KTA1283, KTB764, MPS3638, MPS3638A, PN3638, PN3638A or STB1277.
