Triacs Procurement Notes

Verify the specific suffix 'TP' against official Littelfuse documentation to confirm tape-and-reel packaging requirements. Ensure the ordering part number matches the exact voltage and current ratings required for the target circuit design before finalizing procurement.

Triacs Selection Notes

Select this component when a 400V blocking voltage and 12A continuous current are required in a TO-220-2 package. Compare the 10mA gate trigger specifications against the driving circuit capabilities to ensure reliable turn-on. Verify thermal management needs for the intended operating environment.

Triacs Part Context

This Triac is part of the Qxx12xHx family, designed for general-purpose AC power switching. It shares common characteristics with other devices in the series, such as standardized pinouts and similar thermal resistance profiles, facilitating design consistency across different voltage ratings within the same product line.
