Q6004L3TP

Triacs Overview

The Littelfuse Q6004L3TP is a bidirectional triac in a TO-220 package, rated for 4 A RMS on-state current and 600 V repetitive peak off-state voltage. It features a sensitive gate with a maximum trigger current of 10 mA and a maximum trigger voltage of 1.3 V. The device supports a surge current rating of 55 A and maintains a holding current of 20 mA. Operating temperatures range from -40°C to 125°C, with a peak on-state voltage of 1.6 V and a maximum off-state leakage current of 10 μA.

Triacs Feature Summary

• Integrated Quadrac design combines a triac and diac trigger within a single package to simplify circuit assembly.
• Electrically isolated TO-220 package provides 2500 V rms isolation between leads and mounting surface without external insulators.
• Glass-passivated junctions ensure long-term device reliability and parameter stability.

Triacs Applications

• AC switching and phase control applications
• Speed controls for motors
• Temperature modulation controls
• Lighting controls requiring noise immunity

Triacs Procurement Notes

Verify the specific suffix 'TP' against the manufacturer's official datasheet to confirm packaging details and compliance status. Ensure the selected component matches the required voltage and current ratings for the target AC load application before procurement.

Triacs Selection Notes

Select this component for applications requiring integrated gate triggering to reduce discrete component count. The 600 V rating suits standard mains voltage applications. Verify that the 4 A RMS current capacity meets the load requirements, considering derating for high ambient temperatures up to 125°C.

Triacs Part Context

This part belongs to the Teccor QxxxxLTx series of Quadrac devices developed by Littelfuse. These devices integrate a diac trigger inside the same package as the triac, eliminating the need for separate diac components and assembly steps associated with standard gated triacs.

Triacs Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-reference with L6004L3 variants only if electrical parameters match exactly.

Triacs FAQ
