Q8004R3TP

Triacs Overview

The Littelfuse Q8004R3TP is a bidirectional triac from the Teccor Qxx04xx series, designed for AC power control applications. It features an RMS on-state current of 4 A and a rated repetitive peak off-state voltage of 800 V. The device operates within a junction temperature range of -40°C to +125°C and utilizes a TO-252-3 surface-mount package. 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. Non-repetitive peak on-state currents are specified at 46 A and 55 A, with an on-state voltage of 1.6 V and a maximum off-state leakage current of 10 µA.

Triacs Feature Summary

• Bidirectional switching capability for AC load control
• Surface-mount TO-252-3 package for automated assembly
• High thermal stability across extended operating temperatures

Triacs Applications

• AC motor speed control circuits
• Solid-state relay designs
• Lighting dimmer modules

Triacs Procurement Notes

Verify component authenticity through authorized Littelfuse distributors or direct manufacturer channels. Confirm RoHS compliance status via official datasheets. Ensure storage conditions maintain moisture sensitivity levels appropriate for surface-mount devices. Validate part markings against official specifications to prevent counterfeit infiltration during supply chain acquisition.

Triacs Selection Notes

Select this component when 800 V blocking voltage and 4 A continuous current capacity are required in a compact SMD form factor. Consider the 2.5 V gate trigger voltage for compatibility with standard logic-level drivers. Evaluate thermal management requirements given the TO-252-3 package constraints for high-power dissipation scenarios.

Triacs Part Context

This triac belongs to the Teccor Qxx04xx family, which provides standardized performance metrics for general-purpose AC power switching. The Q8004R3TP variant specifically addresses applications needing robust voltage handling in space-constrained PCB layouts compared to traditional leaded packages.

Triacs Replacement Considerations

Cross-reference with other 800V 4A triacs in TO-252-3 packages from Littelfuse or competitors. Verify identical pinout configurations and thermal resistance values before substitution. Ensure gate trigger characteristics match existing circuit drive capabilities.
