L4X8E6

Triacs Overview

The Littelfuse L4X8E6 is a logic level TRIAC designed for AC switching and phase control applications. It features a 400 V rated repetitive off-state voltage (VDRM) and an RMS on-state current (ITRMS) of 800 mA. The device operates within a temperature range of -65°C to +110°C and utilizes a TO-92-3 through-hole package. Key electrical characteristics include a maximum holding current of 10 mA, a gate trigger voltage of 2 V, and a gate trigger current ranging from 5 mA to 10 mA. It exhibits a typical on-state voltage of 1.6 V and a maximum leakage current of 10 µA at VDRM.

Triacs Feature Summary

• Logic level sensitivity enables direct drive from low-power logic circuits without additional amplification stages.
• Four-quadrant triggering ensures reliable operation regardless of the polarity of main terminal voltage and gate signal.
• Glass-passivated junctions provide long-term parameter stability and protection against environmental degradation.

Triacs Applications

• Lighting controls requiring noise immunity
• Temperature modulation systems
• Speed controls for small motors

Triacs Procurement Notes

Verify the specific ordering suffix E6 to confirm tape-and-reel packaging configuration if required for automated assembly. Confirm RoHS compliance status via the manufacturer's official documentation before integration. Ensure the TO-92-3 lead form matches the target PCB footprint design specifications.

Triacs Selection Notes

Select this component when a compact TRIAC with low gate drive requirements is needed for currents up to 800 mA. The 400 V rating suits low-voltage AC mains applications. Consider the TO-92 package constraints for thermal dissipation in high-duty-cycle scenarios compared to larger power packages.

Triacs Part Context

This part belongs to the LxX8Ex series of Triacs manufactured by Littelfuse under the Teccor brand. The series focuses on providing robust AC switching solutions with integrated noise immunity features suitable for consumer electronics and industrial control panels.

Triacs Replacement Considerations

Consult Littelfuse official substitution guides for equivalent logic-level TRIACs. Verify pinout compatibility and thermal performance metrics when considering alternative manufacturers' components for direct replacement.
