PDF data for the BC328 PNP transistor, the name listing minus 30 V and minus 800 mA ratings, filed under schematics at 53.5 KB. The sheet likely covers both BC327 and BC328, with pinout, package outline, gain groups and maximum ratings. Technicians rely on it when replacing a switching or driver PNP stage and checking that the substitute handles the current. Confirm the collector, base and emitter positions against the PCB silkscreen or footprint, because TO-92 pin order is not universal across makers.
