H11C2W

Triac, SCR Output Optoisolators Overview

The onsemi H11C2W is a single-channel optocoupler featuring a PhotoSCR output, designed for high-voltage isolation applications. It utilizes a six-pin DIP package suitable for through-hole mounting. The device provides an isolation voltage of 5300 Vrms, ensuring robust barrier protection between input and output circuits. Key electrical parameters include a maximum forward current of 60 mA and a typical forward voltage of 1.2 V. The SCR output supports a peak off-state voltage of 200 V and a maximum continuous output current of 300 mA. Operating temperature range spans from -55°C to +100°C, with a power dissipation rating of 1 W.

Triac, SCR Output Optoisolators Feature Summary

• Features a standard six-pin dual in-line package for reliable through-hole PCB integration.

Triac, SCR Output Optoisolators Applications

• Solid-state relay driver circuits for AC load switching
• Industrial control systems requiring isolated gate triggering
• Power supply feedback loops with high-voltage isolation requirements

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific manufacturer source, as historical data indicates distribution under both onsemi and Fairchild trademarks due to corporate acquisitions. Confirm that the component meets RoHS compliance standards if required by your manufacturing process. Ensure the package type matches the intended PCB footprint, specifically the six-pin DIP configuration. Cross-reference datasheet revisions to confirm parameter consistency with current production batches.

Triac, SCR Output Optoisolators Selection Notes

Select this component when high-voltage isolation exceeding 5 kV is required for controlling AC loads directly. The integrated PhotoSCR eliminates the need for external triac drivers, simplifying circuit design. Consider the 60 mA input current limit and 300 mA output capability when sizing drive circuits. Verify thermal management needs given the 1 W power dissipation rating and operating temperature range up to 100°C.

Triac, SCR Output Optoisolators Part Context

The H11C2W belongs to the broader family of optoisolators designed for industrial and consumer applications. It serves as a bridge between low-voltage logic circuits and high-voltage AC power stages. The device is part of a lineage of products originally developed by Fairchild Semiconductor, now maintained under the onsemi portfolio. Its design focuses on reliability and ease of integration into existing power control architectures.

Triac, SCR Output Optoisolators Replacement Considerations

Public confirmed substitute part numbers: H11C1300W (Triac/SCR Output Optocoupler, similar specifications). Note that H11C1300W may have slight variations in packaging or specific electrical ratings; verify compatibility before substitution.
