BC558
by CJ(江苏长电/长晶)The BC558 is a PNP bipolar transistor commonly used for signal switching and amplification. This CJ version is represented as a three-lead, through-hole TO-92 device. Its KiCad download pairs a three-pin symbol with the three-pad TO-92-3_L4.5-W3.5-P1.27-L footprint and includes a 3D model for checking the assembled board view. The library assets came through a real ProtoFlow import and were converted and checked in the editor. Because lead order matters for a transistor, compare the symbol mapping with the specific part documentation during design review. Open the BC558 directly in ProtoFlow.
