IL440-6

Triac, SCR Output Optoisolators Overview

The IL440-6 is a phototriac output optoisolator manufactured by Vishay Semiconductor Opto Division. It consists of a GaAs infrared emitter optically coupled to a silicon planar triac chip with a non-zero crossing network. The device is housed in a 6-pin dual-in-line plastic package. Key electrical specifications include an isolation voltage of 5300Vrms, an output voltage rating of 400V, and a power dissipation of 330mW. It supports currents up to 100 mA RMS.

Triac, SCR Output Optoisolators Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as the part may be obsolete. Ensure packaging integrity matches original specifications. Cross-reference datasheet revisions to confirm pinout and electrical characteristics match design requirements before procurement.

Triac, SCR Output Optoisolators Selection Notes

Select this component for applications requiring non-zero crossing triac isolation. Verify that the 400V output voltage rating meets system peak voltage demands. Ensure the 5300Vrms isolation level satisfies safety standards. Check thermal management needs against the 330mW power dissipation limit. Confirm compatibility with the 6-DIP package footprint.

Triac, SCR Output Optoisolators Part Context

The IL440 series includes variants such as the IL440-4 and IL440-5. These components share similar architectural features but may differ in specific electrical ratings or agency approvals. The IL440-6 specifically denotes the variant with defined non-zero crossing characteristics within the Vishay optoisolator portfolio.

Triac, SCR Output Optoisolators Replacement Considerations

The IL440-6 is listed as obsolete and no longer manufactured. Potential substitutes include other Vishay phototriac optoisolators with matching 6-DIP packages and non-zero crossing features. Verify equivalent isolation voltage and output current ratings when selecting alternatives.
