Q4006L4TP

Triacs Overview

The Littelfuse Q4006L4TP is a bidirectional triac belonging to the Qxx06xx series, designed for AC power control applications. It features a TO-220-2 package and supports an RMS on-state current of 6 A with a rated repetitive off-state voltage (VDRM) of 400 V. The device exhibits a maximum holding current (Ih) of 35 mA and a gate trigger current (Igt) of 25 mA. Key electrical parameters include a maximum non-repetitive peak on-state current of 55 A, a maximum on-state voltage of 1.6 V, and a maximum off-state leakage current of 50 uA at VDRM. It operates within a temperature range of -40°C to +125°C.

Triacs Feature Summary

• Provides reliable AC switching capability in a standard through-hole package suitable for high-current thermal management.
• Features low gate sensitivity for straightforward driver interface compatibility.
• Designed for robust performance across wide industrial operating temperature ranges.

Triacs Applications

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

Triacs Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number Q4006L4TP with official Littelfuse documentation. Ensure the ordering suffix matches the required packaging configuration. Confirm RoHS compliance status via the specific datasheet revision before finalizing procurement orders.

Triacs Selection Notes

Select this component when a 400 V blocking voltage and 6 A continuous current rating are required in a TO-220-2 form factor. Compare the 25 mA gate trigger specification against available drive circuit capabilities. Verify that the 50 uA leakage current meets system isolation requirements.

Triacs Part Context

This triac belongs to the Qxx06xx family from Littelfuse, which groups devices sharing similar current ratings and package styles. The 'Q' prefix typically denotes general-purpose thyristor products within the manufacturer's catalog structure.

Triacs Replacement Considerations

Direct substitutes may include other 400V 6A triacs in TO-220 packages such as the Q4006L4 or equivalent parts from other manufacturers offering identical pinouts and electrical characteristics.
