Overview
The BD705 is a bipolar made by SPTECH in a TO-220C package with 3 pins. 12A 1V 1mA 3MHz 45V NPN TO-220C Bipolar (BJT) ROHS.
PCBKit's library has its KiCad symbol (Pinmap_Generic:Q_NPN_1B_2C_3E, from PCBKit's generic symbols) and its footprint (EasyEDA_Cloud:TO-220-3_L10.2-W4.5-P2.54-L, from EasyEDA), ready for a KiCad board. JLCPCB lists it (part C2907765).
