Q6010L555

Triacs Overview

The Littelfuse Q6010L555 is a Triac belonging to the Qxx10xx series, designed for AC switching and phase control applications. It features a TO-220-3 through-hole package with a flange mount configuration. The device supports an RMS on-state current of 10 A and a rated repetitive off-state voltage (VDRM) of 600 V. Key electrical parameters include a maximum holding current of 50 mA, a gate trigger voltage of 2.5 V, and an on-state voltage of 1.6 V. It operates within a temperature range of -40°C to +125°C.

Triacs Feature Summary

• Integrated diac trigger mechanism eliminates the need for external discrete components in gate circuits.
• Electrically isolated TO-220 package provides 2500 V rms isolation between leads and mounting surface.
• Glass-passivated junctions ensure long-term device reliability and parameter stability.

Triacs Applications

• AC speed controls
• Temperature modulation controls
• Lighting controls requiring noise immunity

Triacs Procurement Notes

Verify the specific suffix against official Littelfuse documentation to confirm exact electrical tolerances and packaging variations. Ensure the procurement channel sources directly from authorized distributors to guarantee component authenticity and traceability. Cross-reference the datasheet revision date with manufacturing lot codes to validate compliance with current RoHS standards and material specifications.

Triacs Selection Notes

Select this component when designing circuits that require integrated gate triggering without additional discrete diacs. The 600 V rating suits standard mains voltage applications, while the 10 A current capacity handles moderate loads. Consider the thermal management requirements associated with the TO-220 flange mount design for sustained operation at high ambient temperatures.

Triacs Part Context

This part belongs to the Teccor Quadrac family developed by Littelfuse. These devices combine a triac and a diac in a single package to simplify circuit assembly. The Qxx10xx series specifically targets general-purpose AC power control, offering a robust alternative to separate triac-diac combinations in consumer electronics and industrial automation systems.
