Its 4000Vrms isolation rating makes it a candidate for galvanic isolation in industrial controls, motor drives, and power-supply feedback loops where the primary-to-secondary barrier must withstand transient overvoltages. The Darlington output with base access gives the designer flexibility to tailor switching speed or add external bias, which is useful when driving logic inputs or relay coils from a low-current microcontroller port. ## 500% minimum CTR — drive margin for low-power inputs A minimum current transfer ratio of 500% at 1 mA forward current. The 1 V typical forward voltage and 60 mA absolute maximum forward current set the LED drive budget. The -55°C to 100°C operating temperature range covers industrial and most commercial environments, though it stops short of the full automotive temperature grade. For a buyer qualifying this part, the active status means standard lead times apply through independent distribution channels — no last-time-buy planning needed.","metaTitle":"IL223AT Optocoupler, 4000Vrms Darlington Output, 8-SOIC","metaDescription":"IL223AT optocoupler: 4000Vrms isolation, Darlington with base output, 500% min CTR at 1mA, surface-mount 8-SOIC.
