Overview
The FS8205 is a MOSFET made by FORTUNE in a SOT-23-6 package with 6 pins. -55℃~+150℃ 1.2V 1W 2 N-Channel 20V 37mΩ@2.5V 6A N-Channel SOT-23-6 MOSFETs ROHS.
PCBKit's library has its KiCad symbol (marbastlib-various:FS8205, from Marbastlib) and its footprint (Package_TO_SOT_SMD:SOT-23-6, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C32254). 70 open-source boards in 60 repositories on GitHub use it.
