Overview
The 2SB857 is a bipolar made by SPTECH in a TO-220C package with 3 pins. 15MHz 1V 1uA 4A 50V PNP TO-220C Bipolar (BJT) ROHS.
PCBKit's library has its KiCad symbol (Pinmap_Generic:Q_PNP_1B_2C_3E, from PCBKit's generic symbols) and its footprint (EasyEDA_Cloud:TO-220F-3_L10.5-W4.7-P2.54-L, from EasyEDA), ready for a KiCad board. JLCPCB lists it (part C2907652).
