Q6008LH1LEDTP

Triacs Overview

The Littelfuse Q6008LH1LEDTP is an 8 Amp Alternistor Triac designed for LED dimmer applications. It features a maximum holding current of 6 mA and operates with a gate trigger current of 10 mA in quadrants I, II, and III. The device supports a repetitive peak off-state voltage (VDRM/VRRM) of 600 V and withstands non-repetitive surge currents up to 85 A at 60 Hz. It utilizes a TO-220AB isolated package with a junction-to-case thermal resistance of 2.8 °C/W. The component functions within a junction temperature range of -40°C to +110°C.

Triacs Feature Summary

• Optimized low load current characteristics specifically for LED lighting applications
• Isolated mounting tab providing high isolation voltage between active terminals
• High commutation performance with di/dt capability of 70 A/µs
• Enables full control of light output at extreme low-end load conditions

Triacs Applications

• AC solid-state switches
• Lighting controls with LED lamp loads
• 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 the exact packing configuration. The datasheet indicates that the TP suffix corresponds to a tube pack containing 50 units per tube. Confirm RoHS compliance status directly from the latest product specifications before finalizing procurement orders.

Triacs Selection Notes

Select this component when designing circuits requiring precise phase control for LED loads with minimal flickering. Ensure the application maintains case temperatures within limits defined by the thermal resistance data. Verify that the gate drive circuit can supply the specified 10 mA trigger current across all operating quadrants for reliable switching.

Triacs Part Context

This part belongs to the Q6008xH1LED series of Alternistor Triacs manufactured by Littelfuse under the Teccor brand. The series includes variants such as the Q6008RH1LED and Q6008NH1LED, which differ primarily in package type and isolation characteristics while maintaining similar electrical ratings for AC switching duties.

Triacs Replacement Considerations

Direct substitutes include the Q6008RH1LEDTP and Q6008NH1LEDTP from the same series. These alternatives share identical electrical parameters but utilize different packages, specifically non-isolated TO-220 or surface-mount D2-PAK configurations.
