Overview
The 2N2905A is a bipolar made by Microchip Technology in a TO-39-3 package with 3 pins. -65℃~+200℃ 1 PNP 1.6V 10uA 3W 5V 600mA 60V 75 PNP TO-39-3 Bipolar (BJT).
PCBKit's library has its KiCad symbol (Transistors:PNP E1 B2 C3, from CERN's library) and its footprint (Package_TO_SOT_THT:TO-39-3, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C2764433). 1 open-source board in 1 repository on GitHub use it.
