TLP291
by TOSHIBA(东芝)Toshiba's TLP291 transfers a signal optically between an LED input and a phototransistor output, providing electrical isolation between circuit sections. It is used in isolated signal interfaces and power-supply feedback circuits. This surface-mount entry uses SOP-4_L4.4-W2.8-P1.27-LS7.0-BR, supplied as a four-pad KiCad footprint. A four-pin schematic symbol and a 3D model complete the free downloadable files, covering the schematic, board layout and assembly view. To verify the conversion, the files from a real ProtoFlow import were converted and checked in the editor. The TLP291 symbol, footprint and model can be opened together directly in ProtoFlow.
