Módulo de Carregamento do Sistema da embarcação solar Guarapuvu II (Zênite Solar)

The BCV27 is a darlington Transistor made by YFW in a SOT-23 package with 3 pins.
PCBKit's library has its footprint (Package_TO_SOT_SMD:SOT-23, from KiCad's library), ready for a KiCad board. 8,841 are in stock at JLCPCB (part C41382624). 6 open-source boards in 5 repositories on GitHub use it.
The library has no symbol for this part yet.
