L4X8E3RP

Triacs Overview

The Littelfuse L4X8E3RP is a bidirectional triac designed for AC power control 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 temperature range of -65°C to +110°C and utilizes a TO-92 through-hole package. Key electrical characteristics include a gate trigger current of 3 mA, a holding current maximum of 5 mA, and an on-state voltage of 1.6 V. It offers a non-repetitive peak on-state current capability of up to 10 A and maintains a low off-state leakage current of 2 µA at the rated voltage.

Triacs Feature Summary

• Bidirectional switching capability for AC circuit control
• High thermal stability with extended operating temperature range
• Low gate sensitivity for efficient triggering

Triacs Applications

• AC motor speed control circuits
• Lighting dimmer applications
• Solid-state relay output stages

Triacs Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct packaging and variant selection. Confirm RoHS compliance status and REACH SVHC declarations prior to integration. Ensure the procurement channel provides authentic Littelfuse components with traceable documentation to prevent counterfeit risks in production environments.

Triacs Selection Notes

Select this component when a 400 V blocking voltage and 800 mA continuous current are required in a compact TO-92 form factor. Evaluate the 3 mA gate trigger requirement against the driving circuit's output capabilities. Consider the thermal management needs given the 110°C maximum junction temperature limit and the specific power dissipation characteristics of the package.

Triacs Part Context

This part belongs to the LxX8Ex series of thyristors from Littelfuse. It is categorized under AC switches and power control devices within the broader semiconductor portfolio. The component serves as a fundamental building block for phase-control applications requiring reliable bidirectional conduction in low-to-medium power scenarios.

Triacs Replacement Considerations

Consult official Littelfuse substitution guides for verified equivalents. Generic replacements may differ in gate sensitivity or thermal resistance. Verify pinout compatibility and voltage ratings before attempting any cross-reference substitution in existing designs.
