Q6004L3

Triacs Overview

The Littelfuse Q6004L3 is a four-quadrant logic level triac designed for AC power control applications. It features a rated average on-state current (Irms) of 4 A and a repetitive peak off-state voltage (VDRM) of 600 V. The device operates within a junction temperature range of -40°C to +125°C and utilizes a TO-220 package for through-hole mounting. Key electrical characteristics include a maximum gate trigger current (Igt) of 10 mA, a maximum gate trigger voltage (Vgt) of 1.3 V, and a peak on-state voltage of 1.6 V. The component supports a surge current rating of 55 A and maintains a maximum holding current (Ih) of 20 mA.

Triacs Feature Summary

• Logic-level sensitivity enables direct drive from low-power digital logic circuits without requiring additional amplification stages.
• Four-quadrant operation ensures reliable triggering across all combinations of main terminal and gate polarities.

Triacs Applications

• Solid-state relays
• AC motor speed controls
• Lighting dimmers

Triacs Procurement Notes

Verify the specific suffix against manufacturer documentation to confirm exact sensitivity class and packaging configuration. Ensure the procurement channel provides original manufacturer traceability. Cross-reference the part number with official Littelfuse databases to validate technical specifications before integration into designs.

Triacs Selection Notes

Select this component when a 4 A RMS current capacity and 600 V blocking voltage are required in a TO-220 form factor. The logic-level gate sensitivity makes it suitable for microcontroller-driven interfaces. Evaluate thermal management requirements based on the 125°C maximum operating temperature limit and the specific load conditions.
