L6004F51

Triacs Overview

The Littelfuse L6004F51 is a four-quadrant logic level triac belonging to the Lxx04xx series, manufactured under the Teccor brand. It features a TO-202AB (TO-92) three-pin package designed for surface or through-hole mounting. The device supports a repetitive peak off-state voltage of 400V and an RMS on-state current of 4A. Key electrical parameters include a gate trigger voltage of 0.7V and a gate trigger current of 10mA, enabling direct interface with standard logic circuits. The component exhibits a holding current of 15mA and maintains a low on-state voltage of 1.6V at rated current.

Triacs Feature Summary

• Logic-level sensitivity allows direct drive from TTL and CMOS logic outputs without additional amplification stages.
• Four-quadrant operation ensures reliable triggering across all combinations of main terminal polarity and gate signal phase.
• Compact TO-202AB packaging facilitates integration into space-constrained control boards and industrial modules.

Triacs Applications

• Solid-state relays requiring compact form factors
• AC motor speed control circuits for small appliances
• Lighting dimmer applications in consumer electronics

Triacs Procurement Notes

Verify the specific suffix 'F51' against the manufacturer's latest datasheet to confirm pinout orientation and marking codes. Ensure the ordering quantity aligns with the manufacturer's standard tube or reel packaging requirements. Confirm RoHS compliance status for the specific production batch prior to final procurement authorization.

Triacs Selection Notes

Select this component when a 400V blocking capability and 4A continuous load current are required within a small footprint. The 0.7V gate trigger threshold makes it suitable for low-voltage logic interfaces. Evaluate thermal management needs based on the TO-202AB package's thermal resistance characteristics for the intended ambient operating conditions.

Triacs Part Context

This part belongs to the Lxx04xx family of logic-level triacs from Littelfuse's Teccor line. These devices are engineered for general-purpose AC power switching where minimal gate drive power is essential. The series offers a balance of high current density and sensitive gate control for modern digital control systems.

Triacs Replacement Considerations

Direct replacements may include other 400V, 4A logic-level triacs in TO-202AB packages from the same manufacturer. Verify that substitute parts match the 0.7V gate trigger voltage and 15mA holding current specifications to ensure circuit compatibility.
