Component datasheet for the 2SB1434 transistor, filed under schematics but in practice a part reference rather than a board diagram. The trailing _E in the name is not explained and may mark an edition or language version. Under the Japanese JIS numbering, the 2SB prefix denotes a PNP bipolar transistor intended for low-frequency work. Before fitting a substitute, a technician uses a sheet like this to confirm the pinout, package outline, voltage and current limits and gain. The 43.9 KB PDF opens in any PDF reader.
