Q6008LH1LED

Triacs Overview

The Littelfuse Q6008LH1LED is an 8 Amp Alternistor Triac designed for LED dimmer applications. It features a maximum holding current of 6 mA and a gate trigger current of 10 mA, ensuring reliable operation with low load currents typical in LED lighting. The device supports a rated repetitive off-state voltage of 600 V and operates within a junction temperature range of -40°C to +110°C. Packaged in an isolated TO-220AB (L-Package), it provides a minimum isolation voltage of 2500 Vrms between the mounting tab and active terminals. Key electrical parameters include a non-repetitive surge peak on-state current of 85 A at 60 Hz, a critical rate of rise of on-state current (di/dt) of 70 A/µs, and a maximum on-state voltage of 1.6 V.

Triacs Feature Summary

• Optimized for low load current characteristics typical in LED lighting applications
• Isolated package design providing high isolation voltage between mounting tab and active terminals
• Low probability of flickering at minimum light output levels
• Enhanced survivability under typical LED load operating conditions

Triacs Applications

• AC solid-state switches
• Lighting controls with LED lamp loads
• Small low current motor speed controls in power tools
• Low current motors in home and brown goods appliances

Triacs Procurement Notes

Verify component authenticity by checking the marking code against official datasheet specifications. Confirm the L-package designation indicates the isolated mounting tab variant. Ensure ordering suffixes match the required packing mode, such as tube packs, as specified in the manufacturer's documentation. Cross-reference agency approval file numbers for regulatory compliance requirements.

Triacs Selection Notes

Select this component when designing circuits requiring reliable commutation at very low load currents. The 6 mA maximum holding current makes it suitable for modern LED drivers that draw minimal steady-state current. Consider the thermal resistance and case temperature limits when determining heat sinking requirements for continuous operation near the 8 A rating.

Triacs Part Context

This part belongs to the Q60xxLH1LED series, which includes variants like the Q6012LH1LED and Q6016LH1LED. These devices share similar low-holding-current characteristics tailored for AC phase control in lighting applications. The series utilizes Alternistor technology to improve safe operating margins compared to standard triacs.

Triacs Replacement Considerations

Direct substitutes within the same family include the Q6008RH1LED and Q6008NH1LED. Note that the RH1LED uses a non-isolated TO-220 package, while the NH1LED uses a TO-263 D2-PAK package. Verify isolation requirements before substituting.
