L4004L6TP

Triacs Overview

The Littelfuse L4004L6TP is a Teccor brand sensitive gate triac designed for AC switching and phase control applications. It features a four-quadrant gating capability, ensuring reliable control in Quadrants I, II, III, and IV, which allows for digital circuitry control with positive or negative pulses. The device is housed in a surface-mount Compak package, offering a low-profile solution suitable for space-constrained designs. It provides voltage capabilities up to 600 V and surge current handling up to 80 A. The component utilizes glass-passivated junctions for long-term reliability and parameter stability. It is RoHS compliant and electrically isolated.

Triacs Feature Summary

Triacs Procurement Notes

Verify the specific suffix 'L6TP' against official Littelfuse documentation to confirm tape-and-reel packaging quantities and lead-free status. Ensure the selected variant matches the required voltage and current ratings for the target application. Cross-reference the part number with authorized distributors to confirm active production status and availability.

Triacs Selection Notes

Select this component when a compact surface-mount triac with sensitive gate drive requirements is needed. The four-quadrant operation makes it suitable for applications requiring bidirectional control from digital logic. Consider the thermal management requirements of the Compak package and ensure the peak repetitive reverse voltage rating exceeds the maximum line voltage peaks in the circuit.

Triacs Part Context

The L4004L6TP belongs to the Teccor line of sensitive gate triacs manufactured by Littelfuse. This series includes devices with current capabilities ranging from 0.8 A to 8 A and voltage ranges from 200 V to 600 V. The product line is characterized by guaranteed gate control in all quadrants and robust junction protection.

Triacs Replacement Considerations

Check for direct replacements within the Teccor L-series or comparable SOT-223 packages if the Compak form factor is not strictly mandatory. Verify that any substitute maintains four-quadrant sensitivity and similar voltage/current ratings.
