Q6006LT

Triacs Overview

The Littelfuse Q6006LT is a Teccor Quadrac device, which integrates a triac and a diac trigger within a single TO-220 package. It features a rated repetitive off-state voltage (VDRM) of 600 V and an on-state RMS current (ITRMS) of 6 A. The device has a maximum holding current (Ih) of 50 mA and a gate trigger current (Igt) of 1.5 A. On-state voltage (VTM) is specified at 1.6 V, with a non-repetitive peak surge current (ITSM) of 80 A at 60 Hz. Leakage current (IDRM) is limited to 10 uA at 25°C. The component operates within a temperature range of -40°C to +125°C.

Triacs Feature Summary

• Integrated Diac Trigger: Combines a triac and diac in one package to eliminate external components and assembly time.
• High Noise Immunity: Designed for AC switching applications requiring reliable operation in electrically noisy environments.
• Electrically Isolated Package: The TO-220 package provides electrical isolation from the mounting surface without additional insulators.

Triacs Applications

• AC speed controls
• Temperature modulation controls
• Lighting controls

Triacs Procurement Notes

Verify the specific suffix against the datasheet to confirm exact triggering characteristics and packaging options. Confirm RoHS compliance status and REACH SVHC declarations prior to integration. Ensure the selected variant matches the required thermal management and isolation specifications for the target application environment.

Triacs Selection Notes

Select this component for phase control circuits where noise immunity is critical. The integrated diac simplifies design by removing the need for discrete trigger components. Verify that the 600V rating and 6A current capacity align with the load requirements. Consider the TO-220 package for through-hole mounting and adequate heat dissipation.

Triacs Part Context

The Q6006LT belongs to the Teccor QxxxxLTx series of Quadrac devices manufactured by Littelfuse. These devices are designed as bidirectional AC switches controlled by gate polarity. The series offers current capacities ranging from 4A to 15A and voltage ratings up to 600V, providing a robust solution for general-purpose AC power control applications.

Triacs Replacement Considerations

The Q6006LTH is a related variant within the same family that eliminates the need for a snubber network. Verify if the snubber-less feature of the LTH variant is suitable for the specific circuit design before substitution.
