Q2004F41

Triacs Overview

The Littelfuse Q2004F41 is a four-quadrant triac belonging to the Q2004F series, designed for AC power control applications. It features a 400V rated repetitive off-state voltage and supports an RMS on-state current of 4A. The device utilizes a TO-202-3 (TO-220AB) through-hole package for robust mounting. Key electrical characteristics include a maximum holding current of 30mA and a gate trigger voltage of 2.5V. It operates within a temperature range of -40°C to +125°C and exhibits a low on-state voltage of 1.6V.

Triacs Feature Summary

• Four-quadrant sensitivity enables reliable triggering across all gate polarities and main terminal voltages.
• High surge current capability provides protection against transient overloads in resistive and inductive loads.
• Through-hole TO-202-3 packaging facilitates secure mechanical attachment and thermal dissipation.

Triacs Applications

• General purpose AC motor speed control circuits
• Solid state relay switching modules
• Lighting dimmer controls for resistive and inductive lamps

Triacs Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package integrity and pin alignment prior to assembly. Ensure storage conditions remain within specified limits to prevent moisture absorption or lead oxidation before soldering.

Triacs Selection Notes

Select this component when a 400V blocking voltage and 4A continuous current rating are required. The TO-202-3 package suits designs needing higher thermal mass than surface-mount options. Verify that the gate trigger requirements align with the driving circuit's output capabilities.

Triacs Part Context

This part belongs to the Q2004F family of general-purpose triacs from Littelfuse. The series offers standardized electrical parameters for industrial AC control. Variations within the family typically differ only by voltage ratings or suffix codes indicating specific testing criteria.

Triacs Replacement Considerations

Direct replacements must match the 4A/400V specification and TO-202-3 footprint. Verify equivalent four-quadrant sensitivity and thermal resistance characteristics to ensure circuit compatibility without redesign.
