Q6008RH1LEDTP

Triacs Overview

The Littelfuse Q6008RH1LEDTP 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 has a rated repetitive off-state voltage (VDRM/VRRM) of 600 V and supports a non-repetitive surge current (ITSM) of 80 A for one cycle at 60 Hz. It operates within a junction temperature range of -40 °C to +110 °C and utilizes a TO-220AB non-isolated package.

Triacs Feature Summary

• Optimized for low load current characteristics typical in LED lighting applications
• High commutation capability with dv/dt rating of 70 V/µs
• UL recognized for 2500 Vrms isolation
• Integrated DIAC functionality available in specific series variants

Triacs Applications

• AC switching and phase control for LED lamp loads
• Dimming controls requiring minimum probability of flickering
• Small low current motor controls in power tools
• Low current motors in home and brown goods appliances

Triacs Procurement Notes

Verify the specific suffix against the manufacturer's official documentation to confirm the exact package type and packing mode. The 'R' suffix indicates a TO-220AB non-isolated mounting tab configuration. Confirm RoHS compliance status directly from the latest datasheet revision before finalizing procurement specifications.

Triacs Selection Notes

Select this component when designing AC phase control circuits for LED loads that require low holding current to prevent premature turn-off. Ensure the thermal management design accounts for the junction-to-case thermal resistance of 1.6 °C/W. Verify that the peak surge current requirements do not exceed the 80 A limit for single-cycle operations at 60 Hz.

Triacs Part Context

This part belongs to the Q6008xH1LED series, which includes variants like Q6008LH1LED and Q6008NH1LED. These devices are specifically engineered to address the challenges of controlling low-current LED loads compared to traditional incandescent bulbs. The series offers different package options including isolated TO-220 and surface-mount D2PAK configurations.

Triacs Replacement Considerations

Q6008LH1LED provides similar electrical characteristics but with an isolated mounting tab package. Q6008NH1LED offers the same performance in a surface-mount TO-263AB (D2PAK) package. Direct pin-for-pin replacement requires matching the isolation requirements of the original design.
