L4X8E6RP

Triacs Overview

The L4X8E6RP is a four-quadrant logic level TRIAC manufactured by Littelfuse, designed for sensitive gate triggering applications. It features an RMS on-state current of 800 mA and a rated repetitive peak off-state voltage of 400 V. The device operates within a junction temperature range of -65°C to +110°C and is housed in a TO-92 through-hole package. Key electrical characteristics include a maximum holding current of 5 mA, a gate trigger voltage of 2 V, and a gate trigger current of 3 mA. The component exhibits a typical on-state voltage of 1.6 V and a non-repetitive peak on-state current capability of 8.3 A or 10 A depending on the pulse width.

Triacs Feature Summary

• Logic-level sensitivity enabling direct drive from low-power digital circuits
• Four-quadrant operation ensuring reliable triggering across all gate polarities
• Robust thermal performance suitable for wide industrial temperature ranges

Triacs Applications

• Lighting control systems requiring low-power gate drive
• Solid-state relay inputs for AC load switching
• Motor speed control circuits for small appliances

Triacs Procurement Notes

Verify the specific suffix E3RP against official Littelfuse documentation to confirm the exact gate trigger current specifications and packaging type. Ensure the procurement channel provides valid RoHS compliance certificates and original manufacturer traceability. Confirm that the TO-92 reel packaging matches the required manufacturing automation standards before finalizing orders.

Triacs Selection Notes

Select this component when a low gate current requirement of 3 mA is necessary for interfacing with microcontrollers or logic gates. Compare the 400 V blocking voltage against the peak line voltage plus transient spikes in the target circuit. Evaluate the 800 mA RMS current rating against the continuous load requirements to ensure adequate thermal margin under worst-case operating conditions.

Triacs Part Context

This part belongs to the LxX8Ex series of TRIACs from Littelfuse, which are optimized for general-purpose AC power control. The series offers various gate sensitivity options to accommodate different driving circuit complexities. The L4X8E6RP specifically targets applications where minimal gate power consumption is critical for system efficiency.

Triacs Replacement Considerations

Consult Littelfuse cross-reference guides for verified equivalents such as other 400V 0.8A logic-level TRIACs in TO-92 packages. Verify pinout compatibility and identical gate trigger parameters before substituting to avoid circuit malfunction.
