Specifications for the 2SA1873 PNP transistor, provided as a 247 KB PDF. The 2SA prefix comes from the JIS semiconductor naming system and denotes a PNP bipolar part, so this is practically a component datasheet even though it is indexed as a schematic. Technicians rely on such sheets for pin identification, package dimensions and voltage, current and power limits when replacing a damaged transistor. If an exact match is unavailable, pick an equivalent with equal or higher ratings and the same footprint and pin order.
