Q6004L452

Triacs Overview

The Q6004L452 is a TRIAC manufactured by Littelfuse, designed for AC switching and phase control applications. It features a maximum repetitive peak off-state voltage of 400V and an on-state RMS current rating of 4A. The device is housed in a TO-220 package with three pins and utilizes a flange mount configuration. Key electrical parameters include a gate trigger voltage typically ranging from 1.3V to 4.0V and a holding current of 25mA. The component is RoHS compliant and UL recognized, ensuring suitability for industrial and consumer electronics requiring reliable bidirectional switching.

Triacs Feature Summary

• Integrated diac trigger mechanism for simplified circuit design
• Electrically isolated mounting surface for enhanced safety
• Glass-passivated junctions for long-term reliability

Triacs Applications

• Lighting controls and dimmers
• Speed controls for AC motors
• Temperature modulation systems

Triacs Procurement Notes

Verify the specific suffix '452' against official Littelfuse documentation to confirm exact voltage and current ratings, as suffixes often denote variations within the QxxxxL series. Ensure compliance with lead-free soldering profiles if required by your manufacturing process. Confirm that the TO-220 flange mount package aligns with your thermal management and PCB layout constraints. Cross-reference agency approvals such as UL recognition for your target market regulations.

Triacs Selection Notes

Select this component when a built-in diac trigger is preferred to eliminate external discrete components. The 400V rating makes it suitable for lower voltage AC mains applications compared to higher voltage variants. Consider the 4A RMS current capacity against your load requirements. The isolated tab simplifies heat sinking without additional insulators, reducing assembly complexity and cost in high-volume production environments.

Triacs Part Context

This part belongs to the Teccor Quadrac series, which combines a triac and a diac in a single package. This integration reduces assembly time and component count compared to using separate gated triacs and diacs. The series is designed for noise-immune AC switching applications, offering a robust solution for phase control circuits where reliability and compactness are critical.

Triacs Replacement Considerations

Direct replacements may include other parts from the QxxxxL series with matching voltage and current ratings, such as Q6004L468 for higher voltage applications. Verify pinout compatibility and thermal resistance characteristics before substitution. Ensure any alternative maintains the integrated diac functionality to preserve circuit simplicity.
