Compact 42.7 KB PDF covering the 2SB1183 transistor. The JIS-style 2SB prefix identifies a PNP device designed mainly for low-frequency circuits, commonly found in power supplies, regulators and amplifier output or driver positions. Although listed under schematics, the file is best treated as component documentation. Before swapping a failed part, check the pinout against the board footprint, because package leads differ between makers, and confirm collector-emitter voltage and collector current limits suit the circuit.
