Q2006L4

Triacs Overview

The Littelfuse Q2006L4 is a Triac belonging to the Qxx06xx series, designed for AC power control applications. It features a 400V repetitive peak off-state voltage and a 6A RMS on-state current rating. The device utilizes a TO-220AB plastic package with an isolated case connection. Key electrical characteristics include a maximum DC gate trigger current of 25 mA and a maximum DC gate trigger voltage of 1.5 V. It exhibits a holding current of 25 mA and supports a critical rate of rise of off-state voltage of 25 V/us. The component is RoHS compliant and lead-free.

Triacs Feature Summary

• Isolated case connection for enhanced safety in grounded mounting configurations
• High dv/dt capability to prevent false triggering during rapid voltage transients
• RoHS compliant construction supporting environmentally conscious manufacturing standards

Triacs Applications

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

Triacs Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct pinout and thermal characteristics. Confirm RoHS compliance status through the latest production documentation. Ensure the TO-220AB package variant matches the required thermal dissipation needs for the target application environment.

Triacs Selection Notes

Select this component when a 400V blocking voltage and 6A continuous current capacity are required for AC switching. The TO-220AB package facilitates direct heatsinking for high-power dissipation scenarios. Verify that the gate trigger requirements align with the driving circuit's output capabilities to ensure reliable turn-on under all operating conditions.

Triacs Part Context

The Q2006L4 is part of Littelfuse's Qxx06xx family of Triacs, which provides standardized performance for general-purpose AC power control. This series offers consistent electrical parameters across different voltage ratings, simplifying design transitions between 200V, 400V, and 600V variants within the same current class.

Triacs Replacement Considerations

Direct replacements within the same series include the Q4006L4TP for higher voltage ratings or the Q6006LH4 for 600V applications. Ensure any substitute maintains the TO-220AB package and isolated case configuration to preserve mechanical and thermal compatibility.
