BC550CTA
by onsemi(安森美)
The onsemi BC550CTA is a three-terminal NPN transistor suited to transistor stages in through-hole circuits. Designers can use a part from this family for switching or signal amplification, subject to the electrical requirements of the circuit. The free KiCad files provide a three-pin schematic symbol and the three-pad TO-92-3_L4.9-W3.7-P2.54-L footprint, along with a 3D model for placement review. Its conversion has been used by 1 ProtoFlow engineer in real designs. Verify the lead mapping against the chosen circuit before routing the board, since the physical footprint and symbol must agree. The part can be opened directly in ProtoFlow.
