L4006V5

Triacs Overview

The Littelfuse L4006V5 is a silicon bilateral voltage-triggered switch, technically classified as a sidac within the manufacturer's component portfolio. It features a TO-251 surface mount package and operates with a logic-sensitive gate configuration. The device is rated for a maximum off-state voltage of 400V and supports an on-state RMS current of 6A. This component provides greater power-handling capabilities compared to standard diacs, serving as a robust trigger element in electronic circuits requiring precise voltage switching.

Triacs Feature Summary

• Silicon bilateral voltage-triggered switch design
• Logic-sensitive gate configuration for reliable triggering
• Enhanced power-handling capabilities relative to standard diacs

Triacs Applications

• Gate triggering for larger thyristors or triacs
• Voltage sensing circuits requiring bilateral switching
• Overvoltage protection trigger mechanisms

Triacs Procurement Notes

Verify component status carefully before integration. Public distributor records indicate that the L4006V5 is discontinued at major retailers such as Digi-Key. Sourcing this specific part number may require checking secondary market availability or evaluating alternative components from the same manufacturer series. Confirm lead times and authenticity through authorized channels prior to finalizing procurement plans.

Triacs Selection Notes

Select this component when a surface-mount bilateral trigger is required with a 400V blocking capability. The TO-251 package suits applications needing compact footprints. Ensure the circuit design accommodates the 6A RMS current rating. Consider the discontinued status in long-term production planning and verify compatibility with existing board layouts and thermal management requirements.

Triacs Part Context

This component belongs to the broader category of power control and sensing solutions offered by Littelfuse. While categorized under TRIACs in some databases, the official description identifies it as a sidac, a type of silicon bilateral switch. It complements the manufacturer's range of fuses, TVS diodes, and other circuit protection devices designed for industrial and consumer electronics.

Triacs Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status, engineers should consult Littelfuse technical support for direct equivalents or evaluate similar sidac devices within the 400V/6A specification range from the same manufacturer.
