Frequently Asked Questions

What is the current transfer ratio of the ILD74-X009T, and how does it affect output drive capability?

The ILD74-X009T has a minimum current transfer ratio (CTR) of 12.5% and a nominal CTR of 35%; this means a 60 mA input forward current produces a minimum 7.5 mA output collector current, which is sufficient to directly drive most logic-level inputs or small relay coils without additional amplification.

How many isolated channels does the ILD74-X009T provide, and can they be driven independently?

The ILD74-X009T provides 2 separate, independent optocoupler channels in a single small outline package; each channel has its own LED input and phototransistor output with no shared circuitry, allowing each channel to isolate a different signal source at up to 20 V collector-emitter with up to 60 mA forward current independently.

What is the dark current specification of the ILD74-X009T, and why is it important in digital isolation designs?

The maximum dark current is 500 nA, which represents the leakage current through the output phototransistor when the LED input is off; keeping dark current below 500 nA ensures that the output logic level remains a valid LOW state in high-impedance circuits, preventing false triggering in sensitive microcontroller inputs operating at 3.3 V or 5 V.

Is the Vishay ILD74-X009T suitable for use in UL-recognized safety-critical applications?

Yes, the ILD74-X009T carries UL recognition, making it compliant for use in UL-listed end products that require optocoupler isolation for operator safety; it operates with a 1.5 V maximum forward voltage and is rated for industrial temperature ranges, supporting deployment in control panels and communication interfaces requiring documented component safety certification.
