Q6010LTH

Triacs Overview

The Littelfuse Q6010LTH is a Quadrac device, integrating a triac and an internal diac trigger within a single package. It operates as a bidirectional AC switch with a rated repetitive off-state voltage (VDRM) of 600 V and an on-state RMS current (IT(RMS)) of 10 A. The device features glass-passivated junctions for parameter stability and reliability. It is housed in an electrically isolated TO-220 package, providing isolation up to 2500 V rms from the leads to the mounting surface. This integration eliminates the need for external discrete diacs and snubber networks, simplifying circuit design for AC switching applications.

Triacs Feature Summary

• Integrated diac trigger mechanism eliminates the requirement for external discrete triggering components.
• Snubberless operation capability reduces component count and simplifies thermal management.
• Electrically isolated TO-220 package provides high-voltage isolation between leads and mounting surface.

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 pinout and isolation ratings. Ensure the selected variant matches the required voltage and current specifications for the target application. Cross-reference datasheets to confirm RoHS compliance status and package isolation characteristics before finalizing procurement.

Triacs Selection Notes

Select this component when designing circuits that require integrated gate triggering without external diacs. The snubberless feature makes it suitable for applications where minimizing passive components is critical. Verify that the 600 V blocking voltage and 10 A current rating exceed the maximum load requirements of the intended AC control system.

Triacs Part Context

This part belongs to the QxxxxLTx series of Quadrac devices developed by Littelfuse under the Teccor brand. These devices combine triac and diac functions into one package to save assembly time and cost. The series covers various current capacities and voltage ratings for general AC switching needs.

Triacs Replacement Considerations

Direct replacements must be other Quadrac devices with integrated diacs. Verify that substitute parts maintain the same TO-220 isolation rating and snubberless operation capabilities. Check for equivalent VDRM and IT(RMS) values to ensure compatibility with existing circuit designs.
