PNP transistor documentation for the 2SA1150, provided as a 193 KB PDF. JIS naming uses 2SA for PNP bipolar devices, so although indexed as a schematic the file almost certainly holds datasheet specifications for that part alone. Repair technicians rely on it to verify pin assignment, package style and maximum voltage, current and dissipation before replacing a failed transistor. It also helps when hunting for an equivalent. Check the rank suffix on the original, since gain classes can matter in matched or biased circuits.
