Boards using the BC858B

4 boards

Boards in 2 GitHub repositories, designed in KiCad, that use the BC858B by BORN (-55℃~+150℃ 1 PNP 100MHz 100mA 100nA 200 200mW 30V 500mV 5V PNP Standalone SOT-23 Bipolar (BJT) ROHS). See how each wires it, with its parts, size, README and files; the BC858B’s symbol, footprint and pinout are on its own page.
