L6004L356

Triacs Overview

The Littelfuse L6004L356 is a four-quadrant logic level TRIAC designed for AC switching and phase control applications. It features a 600V repetitive peak off-state voltage (V(DRM)) and an RMS on-state current rating of 4A. The device utilizes sensitive gate triggering with a gate trigger current range of 3-3-3-3mA, enabling direct interface with low-power logic circuits. Packaged in a TO-220AB isolation mount, it provides robust thermal management and electrical isolation for industrial and consumer power control systems.

Triacs Feature Summary

• Four-quadron logic level operation for versatile gate triggering across all main terminal polarities
• Integrated heat sink mounting capability via TO-220AB package for efficient thermal dissipation
• Sensitive gate design allowing direct drive from standard logic families without additional amplification

Triacs Applications

• Solid state relays requiring high isolation and logic compatibility
• Lighting dimmer circuits for residential and commercial fixtures
• Motor speed control systems for small appliances

Triacs Procurement Notes

Verify the specific suffix designation against the manufacturer's current datasheet to confirm exact gate sensitivity and packaging variations. Ensure the procurement channel sources directly from authorized Littelfuse distributors to guarantee component authenticity and traceability. Cross-reference the part number with the latest product change notifications to account for any manufacturing updates or compliance modifications.

Triacs Selection Notes

Select this component when a 600V blocking voltage and 4A continuous current capacity are required for AC load switching. The logic-level gate sensitivity makes it suitable for designs where microcontroller or TTL outputs must directly control higher power loads. Consider the TO-220AB package for applications necessitating direct mounting to external heatsinks for improved thermal performance under sustained load conditions.

Triacs Part Context

This device belongs to the Teccor L6004 series of four-quadrant TRIACs manufactured by Littelfuse. The series is characterized by its ability to handle AC power switching with minimal gate drive requirements. It serves as a core semiconductor switch in power electronics, bridging low-voltage control signals with high-voltage AC mains or motor loads in various industrial and consumer applications.

Triacs Replacement Considerations

Compatible substitutes include the L6004L3TP and L6004L3V. Verify that replacement parts maintain the same 600V V(DRM), 4A I(T)RMS, and TO-220AB package dimensions to ensure mechanical and electrical compatibility within the existing circuit design.
