Q8006LH4TP

Triacs Overview

The Littelfuse Q8006LH4TP is a bidirectional triac belonging to the Qxx06xxH series, designed for AC power control applications. It features an RMS on-state current (IT(RMS)) of 6 A and a non-repetitive peak on-state current capability of 80 A or 85 A depending on pulse duration. The device supports a rated repetitive peak off-state voltage (VDRM) of 800 V with a maximum off-state leakage current of 10 µA at VDRM. Key gate parameters include a maximum holding current (IH) of 35 mA, a gate trigger voltage (VGT) of 1.3 V, and a gate trigger current (IGT) of 35 mA. The on-state voltage drop is specified at 1.6 V.

Triacs Feature Summary

• Bidirectional conduction capability suitable for alternating current switching
• High voltage blocking rating for robust off-state performance
• Defined gate trigger characteristics for reliable firing

Triacs Applications

• AC motor speed control circuits
• Solid state relay output stages
• Lighting dimmer applications

Triacs Procurement Notes

Verify the specific suffix 'H4TP' against the manufacturer's latest datasheet to confirm package type and tape-and-reel specifications. Ensure the component meets RoHS and REACH compliance requirements for your target market. Cross-reference the exact part number with authorized distributors to avoid counterfeit components. Confirm thermal management requirements based on the 6 A RMS rating and ambient operating conditions.

Triacs Selection Notes

Select this component when an 800 V blocking voltage and 6 A continuous current are required in a bidirectional configuration. Compare the 35 mA gate trigger current against available drive circuit capabilities to ensure sufficient triggering power. Evaluate the 1.6 V on-state voltage for thermal dissipation calculations under load. Consider the Qxx06xxH series alternatives if different current ratings or voltage classes better suit the system design constraints.

Triacs Part Context

This part belongs to the Qxx06xxH series of bidirectional triacs from Littelfuse. The series offers various combinations of current and voltage ratings within the same family structure. The Q8006 designation indicates the specific 6 A / 800 V variant within this product line.

Triacs Replacement Considerations

Check for direct cross-reference part numbers from other manufacturers offering equivalent 6 A, 800 V bidirectional triacs. Verify pinout compatibility and package dimensions before substitution. Ensure replacement devices meet or exceed the original gate trigger current and voltage specifications.
