Q6008LTH1LEDTP

Triacs Overview

The Littelfuse Q6008LTH1LEDTP is an Alternistor Quadrac designed for AC switching and phase control applications, specifically optimized for LED lighting loads. It integrates a Triac and a DIAC trigger into a single TO-220AB package with an isolated mounting tab. The device features an RMS on-state current of 8 A and a rated repetitive off-state voltage of 600 V. The internal DIAC has a breakover voltage range of 33 V to 43 V. Maximum holding current is specified at 6 mA, ensuring reliable operation with low-current LED loads. The component operates within a junction temperature range of -40°C to +110°C.

Triacs Feature Summary

• Integrates a Triac and DIAC trigger in a single package to simplify circuit design
• Low maximum holding current of 6 mA optimized for LED load characteristics
• Electrically isolated TO-220AB package facilitates external heat sinking
• High surge capability with di/dt performance of 70 A/µs

Triacs Applications

• Light dimmers with LED loads
• AC solid-state switches
• Small low current motors in power tools
• Low current motors in home appliances

Triacs Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details. The TP suffix indicates tube packing with a base quantity of 500 units per tube. Ensure compliance with RoHS directives and check for any agency approvals relevant to the target market before finalizing procurement specifications.

Triacs Selection Notes

Select this component when designing circuits requiring integrated triggering for AC phase control. The low holding current specification makes it suitable for driving LED loads that draw minimal steady-state current. Verify that the application's peak non-repetitive surge current requirements remain within the 80 A to 85 A limits depending on line frequency.

Triacs Part Context

This part belongs to the Q6008LTH1LED series of Alternistor Quadracs manufactured by Littelfuse under the Teccor brand. The series is engineered to address the specific challenges of controlling modern LED lighting, which typically exhibits lower load currents compared to traditional incandescent bulbs.

Triacs Replacement Considerations

Direct replacements must match the 8 A current rating, 600 V voltage rating, and integrated DIAC functionality. Verify that alternative components maintain the 6 mA maximum holding current requirement to ensure compatibility with low-power LED loads without flickering.

Triacs FAQ

What is the function of the integrated DIAC in this device?

The integrated DIAC provides internal triggering for the Triac, eliminating the need for a discrete DIAC component and simplifying the circuit layout.

How does the holding current specification benefit LED applications?

The maximum holding current of 6 mA allows the device to remain latched and conduct properly even when driving LED loads that draw very low steady-state currents.

What is the isolation voltage between the mounting tab and active terminals?

The device offers a minimum isolation voltage of 2500 V AC between the mounting tab and the active terminals (MT1 and MT2).
