About this part
Optocoupler for isolating control logic from mains-side circuitry, and the usual choice in SMPS feedback loops. 5 kV rms isolation and a wide current transfer ratio range make it tolerant of production spread.
Available in DIP and SOP-4 variants; we quote both when the assembly is being reflowed rather than wave soldered.
