BC547
by CJ(江苏长电/长晶)
For general discrete stages, the BC547 provides a familiar through-hole NPN transistor option for signal amplification, buffering, and switching. The part uses three leads in a TO-92-style body; this record's footprint has the tighter pitch encoded by its exact library name. Supplied KiCad assets comprise a 3-pin BC547 symbol, the TO-92-3_L4.9-W3.7-P1.27-L footprint with 3 pads, and an included 3D representation. The conversion has been used by 5 ProtoFlow engineers in real designs, so it has practical usage history alongside editor verification. The BC547 component can be opened directly in ProtoFlow to continue schematic or PCB work.
