L6004L3

Triacs Overview

The Littelfuse L6004L3 is a four-quadrant logic level TRIAC designed for AC power control applications. It features a rated repetitive peak off-state voltage of 600V and an RMS on-state current of 4A. The device utilizes sensitive gate triggering with a maximum gate trigger current of 3mA, enabling direct interface with low-power logic circuits. Packaged in a TO-220AB through-hole housing, it supports operating temperatures from -40°C to +110°C. Key electrical parameters include a non-repetitive peak on-state current of 33A or 40A depending on the specific variant, a holding current maximum of 5mA, and a typical on-state voltage of 1.6V.

Triacs Feature Summary

• Four-quadrant sensitivity allows reliable triggering across all gate polarities and MT2 polarities.
• Logic-level compatibility enables direct drive from standard TTL or CMOS logic outputs without additional amplification.
• Sensitive gate architecture minimizes required gate drive current for efficient circuit design.

Triacs Applications

• Solid-state relays requiring compact switching solutions
• General-purpose AC motor speed control circuits
• Lighting dimmer applications for resistive and inductive loads

Triacs Procurement Notes

Verify the exact suffix (e.g., TP, V) when ordering, as these indicate specific package variations or testing standards within the L6004L3 family. Confirm that the selected variant matches the required thermal management capabilities for the intended application environment. Ensure the supplier provides official datasheets to validate the specific electrical characteristics of the purchased component batch.

Triacs Selection Notes

Select this component when a 4A RMS current rating at 600V is sufficient for the load requirements. The sensitive gate characteristic makes it suitable for microcontroller-driven systems where output current is limited. Consider the TO-220 package size for adequate heat dissipation if continuous high-current operation is expected. Verify that the 5mA holding current meets the minimum load current requirements of the specific AC circuit to prevent unintended turn-off.

Triacs Part Context

The L6004L3 belongs to the Lxx04xx series of TRIACs manufactured by Littelfuse under the Teccor Electronics brand. This series is characterized by robust construction for industrial and consumer power control needs. The part shares functional similarities with other 4A/600V TRIACs but is distinguished by its specific logic-level gate sensitivity and four-quadrant operation capabilities.

Triacs Replacement Considerations

Potential substitutes include the L6004L3TP and L6004L3V. These variants share the same core electrical specifications but may differ in packaging details or specific manufacturer testing criteria. Cross-reference the pinout and thermal resistance values before implementation to ensure mechanical compatibility.
