Overview
The MMBT3906W is a bipolar Transistors BJT made by Doeshare in a SOT-323-3 package with 3 pins. 200mA 200mW 40V 50nA 5V SOT-323-3 Bipolar (BJT) ROHS.
PCBKit's library has its KiCad symbol (Transistor_BJT:MMBT3906, from KiCad's library) and its footprint (Package_TO_SOT_SMD:SOT-323_SC-70, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C2931643).
