EL817S1
by EVERLIGHT(亿光)Optical isolation is the purpose of EVERLIGHT's EL817S1: an LED input controls a phototransistor output without a direct electrical signal path between them. This surface-mount optocoupler is commonly used for power-supply feedback and isolated control inputs, passing a signal between electrically separated circuits. Already, 2 ProtoFlow engineers have used this conversion in real designs. Its free KiCad package contains a 4-pin symbol and the SOP-4_L6.5-W4.6-P2.54-LS10.2-TL footprint with 4 pads, plus a 3D model. Bring EL817S1 directly into ProtoFlow by opening this entry.
