Q6004F31

Triacs Overview

The Littelfuse Q6004F31 is a four-quadrant TRIAC designed for AC power control applications. It features a 400V repetitive peak off-state voltage and an RMS on-state current rating of 4A. The device utilizes a TO-220AB insulated flange mount package, providing electrical isolation between the terminals and the mounting surface. Key electrical characteristics include a maximum gate trigger current of 50mA and a holding current of 30mA. It operates within a temperature range of -40°C to +125°C and supports non-repetitive surge currents up to 55A.

Triacs Feature Summary

• Four-quadrant sensitivity enables reliable triggering across all gate polarities and MT2 polarities.
• Insulated flange mount construction provides electrical isolation for direct heatsink attachment.
• High surge current capability allows handling of inductive load turn-on transients.

Triacs Applications

• Solid state relays
• Motor speed controls
• Lighting dimmers

Triacs Procurement Notes

Verify the specific suffix 'F31' against official Littelfuse documentation to confirm pinout orientation and insulation class. Ensure the procurement channel sources from authorized distributors to guarantee component authenticity and traceability. Cross-reference the datasheet revision date with manufacturing lot codes to ensure compliance with current environmental standards.

Triacs Selection Notes

Select this component when a 400V blocking voltage and 4A continuous current are required in an insulated package. Compare the 50mA gate trigger requirement against available drive circuit capabilities. Evaluate thermal management needs based on the TO-220AB package's thermal resistance characteristics and the expected ambient operating temperature.

Triacs Part Context

This part belongs to the Teccor Q series of TRIACs, widely used in general-purpose AC switching. The Q6004F31 variant specifically denotes the 400V voltage rating and the F31 package configuration. It serves as a robust solution for replacing older thyristor technologies in consumer electronics and industrial control panels requiring galvanic isolation.

Triacs Replacement Considerations

Direct replacements must match the 4A/400V rating and TO-220AB insulated form factor. Verify that substitute parts maintain identical four-quadrant triggering sensitivity and similar holding current specifications to ensure circuit stability without modification.
