Q6004R4

Triacs Overview

The Littelfuse Q6004R4 is a standard Triac belonging to the Teccor Qxx04xx series, designed for general-purpose AC power control applications. It features a rated repetitive off-state voltage (VDRM) of 600 V and an on-state RMS current (IT(RMS)) of 4 A. The device operates within a junction temperature range of -40°C to +125°C and utilizes a TO-220AB package with three pins. Key electrical characteristics include a maximum holding current of 30 mA, a gate trigger voltage of 2.5 V, and a gate trigger current ranging from 25 mA to 50 mA. The component exhibits a typical on-state voltage of 1.6 V and a non-repetitive peak on-state current capability of 46 A or 55 A depending on pulse duration.

Triacs Feature Summary

• Standard switching speed suitable for general AC load control
• Robust thermal performance in isolated flange mount packages
• High surge current handling capability for inductive loads

Triacs Applications

• Solid state relays
• Motor speed controls
• Lighting dimmers

Triacs Procurement Notes

Verify the specific suffix against official Littelfuse documentation to confirm pinout orientation and packaging type. Confirm RoHS compliance status and lead-free plating requirements prior to integration. Ensure the ordering quantity matches the manufacturer's minimum reel or tube specifications.

Triacs Selection Notes

Select this component when a 600 V blocking voltage and 4 A continuous current rating are required for AC switching. The TO-220AB package facilitates heatsinking for higher power dissipation scenarios. Verify that the gate drive circuit can supply the specified 25 mA to 50 mA trigger current reliably across the operating temperature range.

Triacs Part Context

This part belongs to the Littelfuse Teccor Qxx04xx family of standard Triacs. These devices are widely used in industrial and consumer appliances for phase control. The Q6004R4 specifically denotes the 600 V, 4 A variant within this standardized product line.

Triacs Replacement Considerations

Check for direct equivalents such as the Q6004L468 or Q6004V4TP, ensuring identical voltage, current ratings, and compatible package dimensions for mechanical fit.
