Triacs Procurement Notes

Verify the exact suffix against official Littelfuse documentation to confirm pinout and electrical tolerances. Ensure the component matches the required voltage and current ratings for the specific circuit design before integration.

Triacs Selection Notes

Select this component when a compact surface-mount solution is required for moderate AC current switching. Compare the 400 V rating against peak line voltages and ensure the TO-252 package thermal resistance meets the system's heat dissipation requirements.

Triacs Part Context

This part belongs to the Littelfuse QJ series of thyristors, which are engineered for general-purpose AC power switching. The series offers various voltage and current ratings in standardized packages to facilitate design flexibility across consumer and industrial electronics.

Triacs Replacement Considerations

Consult Littelfuse datasheets for direct replacements within the QJxx06xH family or equivalent triacs from other manufacturers with matching 6A/400V specifications and TO-252 footprints.
