L6004L8TP

Triacs Overview

The Littelfuse L6004L8TP is a single-phase triac designed for AC power control applications. It features a 600V repetitive peak off-state voltage and a 4A RMS on-state current rating. The device utilizes a four-quadrant gate trigger sensitivity with specified currents of 10mA, 10mA, 10mA, and 20mA across different quadrants. Packaged in a TO-251AA (DPAK) surface-mount case, it offers a compact solution for high-density circuit designs. Key electrical limits include a maximum DC gate trigger current of 20mA, a holding current of 15mA, and a maximum leakage current of 0.2mA.

Triacs Feature Summary

• Four-quadrant gate triggering ensures reliable turn-on regardless of the polarity of the gate signal or main terminal voltage.
• Surface-mount TO-251AA package facilitates automated assembly and reduces footprint in power control circuits.
• High thermal stability supports operation in demanding industrial and consumer environments.

Triacs Applications

• Solid-state relays
• Lighting dimmers
• Motor speed controls

Triacs Procurement Notes

Verify the specific suffix 'L8' against the manufacturer's official datasheet to confirm exact sensitivity grades and packaging variations. Ensure compliance with RoHS directives if required by the target market. Cross-reference the TO-251AA pinout with the PCB layout to prevent installation errors during assembly.

Triacs Selection Notes

Select this component when a 600V blocking capability and 4A continuous load current are required in a surface-mount form factor. Evaluate the thermal resistance of the PCB copper area to ensure junction temperatures remain within safe operating limits under full load conditions. Consider the gate trigger sensitivity requirements of the driving circuitry to guarantee robust switching performance.

Triacs Part Context

This part belongs to the Littelfuse triac family, which provides various voltage and current ratings for AC switching needs. The L6004 series specifically targets mid-power applications requiring reliable phase control. The TO-251AA package distinguishes it from through-hole alternatives like TO-220AB, offering advantages in space-constrained designs.

Triacs Replacement Considerations

Direct replacements must match the 600V/4A rating and TO-251AA package. Verify that substitute devices offer equivalent four-quadrant sensitivity and similar thermal characteristics to maintain circuit performance without redesign.
