L4006L6TP

Triacs Overview

The L4006L6TP is a logic-sensitive TRIAC manufactured by Littelfuse Inc., designed for AC power control applications. It features a maximum off-state voltage of 400V and a maximum load current rating of 6A. The device utilizes a TO-220AB (TO-220-3) through-hole package, suitable for flange mounting. Key electrical characteristics include a gate trigger current of 10mA, with specific sensitivity levels defined as 5-5-5-10mA. This component is classified as a standard TRIAC with logic-compatible gate triggering, ensuring reliable operation in low-power drive circuits.

Triacs Feature Summary

• Logic-sensitive gate triggering for compatibility with low-current digital outputs
• Robust 6A continuous load current handling capability
• High voltage blocking capacity rated at 400V
• Through-hole TO-220AB package design for secure thermal management

Triacs Applications

• AC motor speed control systems
• Solid-state relay implementations
• Lighting dimmer circuit designs
• Heating element regulation

Triacs Procurement Notes

Verify the exact datasheet version from Littelfuse to confirm the 5-5-5-10mA sensitivity profile and TO-220AB pinout. Ensure the application environment supports the 400V rating and that heat sinking requirements for the 6A current are met. Confirm RoHS3 compliance status if required by project specifications.

Triacs Selection Notes

Select this component when a logic-level interface is required for AC switching. The 10mA gate trigger current allows direct interfacing with many microcontrollers or logic ICs without additional driver stages. The TO-220 package offers better thermal dissipation than surface-mount alternatives for higher current loads.

Triacs Part Context

This part belongs to the Littelfuse family of sensitive gate TRIACs. It is distinct from high-gate-sensitivity variants and standard gate types. The 'L6' suffix typically denotes the specific gate sensitivity class and package type within the manufacturer's nomenclature system.

Triacs Replacement Considerations

Direct substitutes may include other 400V/6A logic TRIACs in TO-220 packages from manufacturers like STMicroelectronics or Vishay, provided the gate trigger current matches the 10mA requirement.
