The BCP51 is a bipolar made by Nexperia in a SOT-223 package with 3 pins. -55℃~+150℃ 1 PNP 1.35W 100nA 145MHz 1A 45V 500mV 5V 63 PNP SOT-223 Bipolar (BJT) ROHS.
PCBKit's library has its KiCad symbol (Transistor_BJT:BCP51, from KiCad's library) and its footprint (Package_TO_SOT_SMD:SOT-223-3_TabPin2, from KiCad's library), ready for a KiCad board. 2,266 are in stock at JLCPCB (part C15335). 6 open-source boards in 6 repositories on GitHub use it.
