BC559CTA

by onsemi(安森美)BC559CTA belongs to the BC559 family of PNP small-signal bipolar transistors, commonly used in analog amplification and switching stages. The onsemi part is supplied here with a through-hole TO-92 library representation, useful for boards assembled with leaded components. A three-pin schematic symbol accompanies the three-pad TO-92-3_L4.9-W3.7-P2.54-L footprint in the free KiCad download. An included 3D model supports a visual check of the transistor body within the board assembly. These files originate from a real ProtoFlow import that was converted and checked in the editor. The complete entry can also be opened directly in ProtoFlow.
