Overview
The 2SB649 is a bipolar made by Jiangsu Changjing Electronics Technology (CJ) in a TO-126 package with 3 pins. -55℃~+150℃ 1 PNP 1.5A 10uA 120V 140MHz 1V 1W 5V 60 PNP TO-126 Bipolar (BJT) ROHS.
PCBKit's library has its KiCad symbol (Pinmap_Generic:Q_PNP_1E_2C_3B, from PCBKit's generic symbols) and its footprint (EasyEDA_Cloud:TO-126_L8.3-W3.5-P2.29-T, from EasyEDA), ready for a KiCad board. JLCPCB lists it (part C16056).
