Q6004D3TP

Triacs Overview

The Littelfuse Q6004D3TP is a bidirectional triac in the Teccor Qxx04xx series, housed in a TO-252-3 (DPAK) surface-mount package. It supports an RMS on-state current of 4 A and a rated repetitive peak off-state voltage of 600 V. The device exhibits a maximum on-state voltage of 1.6 V and a gate trigger voltage of 2 V with a gate trigger current range of 10 mA to 25 mA. Non-repetitive peak on-state currents are specified at 46 A and 55 A. Operating temperatures range from -40°C to +110°C, with a maximum holding current of 20 mA.

Triacs Feature Summary

• Integrated phase control capability for AC power switching applications
• Glass-passivated junctions designed for parameter stability and long-term reliability
• Surface-mount construction compatible with automated pick-and-place assembly processes

Triacs Applications

• AC motor speed control circuits
• Solid-state relay implementations
• Lighting dimmer and modulation controls

Triacs Procurement Notes

Verify component authenticity through authorized Littelfuse distributors or certified suppliers. Confirm RoHS compliance status and REACH SVHC declarations against the latest manufacturer documentation. Validate lot traceability and ensure storage conditions maintain device integrity prior to soldering.

Triacs Selection Notes

Select this part for designs requiring a 600 V blocking voltage and 4 A continuous current handling in a compact SMD footprint. Ensure the driving circuit can supply the specified 10 mA to 25 mA gate trigger current. Verify that the thermal management strategy accommodates the +110°C maximum junction temperature limit during operation.

Triacs Part Context

This component belongs to the Littelfuse Teccor Qxx04xx family of standard triacs. These devices are engineered for general-purpose AC switching tasks. The TO-252-3 package provides a balance between current capacity and board space efficiency compared to larger through-hole alternatives.

Triacs Replacement Considerations

Evaluate the QJ6004D3RP for direct pin-compatible replacement if surface-mount topology is required, noting its 400 V rating differs from the 600 V specification of the Q6004D3TP.
