Triacs Procurement Notes

Verify the exact part number against official Littelfuse documentation, as standard series listings often use Q4016LH6TP. Confirm RoHS compliance status through the manufacturer's latest product change notifications. Ensure the supplier provides valid traceability for the TO-220-2 package variant. Cross-reference datasheet revisions to confirm gate trigger characteristics match the 80-80-80mA specification required for your design.

Triacs Selection Notes

Select this component when designing circuits requiring 400V blocking capability and 16A continuous current handling. The TO-220-2 package is suitable for applications needing direct heatsinking or high thermal dissipation. Verify that the gate trigger current aligns with your driver circuit's output capabilities. Consider the 1.6V on-state voltage for efficiency calculations in high-power AC control scenarios.

Triacs Part Context

This triac belongs to the Qxx16xHx series from Littelfuse, a line focused on general-purpose AC power control.
