Q6006LH3

Triacs Overview

The Littelfuse Q6006LH3 is a TECCOR brand triac designed for general-purpose AC power control applications. It features a non-insulated TO-220AB (TO-220-2) package suitable for through-hole mounting. The device supports a rated repetitive off-state voltage of 600 V and an RMS on-state current of 6 A. Key electrical parameters include a maximum holding current of 50 mA, a gate trigger current of 1.5 A, and a typical on-state voltage of 1.6 V. It operates within a junction temperature range of -40°C to +125°C.

Triacs Feature Summary

• High surge capability with non-repetitive peak on-state current ratings up to 80 A
• Gate turn-off functionality enabled by specific gate trigger characteristics
• Robust thermal performance in standard TO-220AB leaded packages

Triacs Applications

• AC motor speed controls
• Solid state relays
• Lighting dimmers

Triacs Procurement Notes

Verify the exact suffix against official Littelfuse documentation to confirm pinout and packaging variations. Ensure compatibility with existing thermal management designs given the TO-220AB form factor. Cross-reference datasheet revisions to confirm compliance with current environmental directives before finalizing component selection.

Triacs Selection Notes

Select this component when a 6 A RMS current rating at 600 V is required for AC switching. Consider the high gate trigger current requirement of 1.5 A when designing the drive circuitry. Evaluate thermal dissipation needs based on the specific ambient operating conditions and heat sink availability for the TO-220 package.

Triacs Part Context

This part belongs to the Littelfuse TECCOR Q series of triacs, which are widely used in industrial and consumer AC power control circuits. The Q6006LH3 variant specifically targets applications requiring moderate current handling with robust surge tolerance. It serves as a direct replacement for legacy components in similar voltage and current classes.

Triacs Replacement Considerations

The Q6006LTHTP is listed as an alias or alternative packaging variant for this part number family. Verify pin compatibility and thermal resistance values when substituting with other 6A/600V triacs from different manufacturers.
