EL817B-F
by EVERLIGHT(亿光)Isolated control inputs and power-supply feedback paths are typical applications for EVERLIGHT's EL817B-F. This optocoupler combines an LED input with a phototransistor output to pass a signal across an electrical isolation barrier. For verification, the conversion has seen use by 2 ProtoFlow engineers in real designs. The supplied CAD entry represents the through-hole DIP version: its free KiCad files include a 4-pin symbol, the DIP-4_L6.5-W4.6-P2.54-LS7.6-BL-1 footprint with 4 pads, and a 3D model. These assets cover schematic placement, PCB layout, and viewing the component in an assembly. EL817B-F can also be opened directly in ProtoFlow.
