PC357C
by UMW(友台半导体)The PC357C from UMW is a transistor-output optocoupler for passing signals across an electrical isolation boundary. It combines an optical input with a transistor output, making the family useful for isolated interfaces and power-supply feedback. For this record, the free KiCad download provides a four-pin symbol and the four-pad SOP-4_L3.6-W4.4-P2.54-LS7.0-TL_PC357N3J000F surface-mount footprint. The footprint identifier is retained exactly as supplied, and a 3D model is included for assembly visualization. A real import into ProtoFlow was converted and checked in the editor to verify the files. The PC357C can be opened directly in ProtoFlow.
