BC547B
by LGE(鲁光)Small-signal switching and amplification are typical jobs for the BC547B, LGE's NPN bipolar transistor in this record. Its through-hole TO-92 package suits discrete transistor stages where the base, collector, and emitter are wired individually in the schematic. A free KiCad download provides a 3-pin symbol and the TO-92-3_L4.9-W3.7-P1.27-L footprint with 3 pads. A 3D model is supplied as well, allowing the package position to be reviewed with the rest of the board assembly. 3 ProtoFlow engineers have used the conversion in real designs. To place this BC547B representation in a project, open it directly in ProtoFlow.
