QJ6004D4RP

Triacs Overview

The Littelfuse QJ6004D4RP is a bidirectional triac in the QJxx04xx series, rated for 600 V repetitive peak off-state voltage and 4 A RMS on-state current. It features a maximum holding current of 30 mA and a gate trigger current range of 25 mA to 50 mA with a gate trigger voltage of 1.3 V. The device operates within a junction temperature range of -40 °C to +150 °C and exhibits an on-state voltage of 1.4 V. Packaged in a surface-mount TO-252-3 (D-PAK) case, it offers low leakage current of 5 µA at rated voltage.

Triacs Feature Summary

• High thermal stability supporting operation up to 150 °C
• Sensitive gate triggering capability for efficient control circuits
• Robust construction designed for industrial power switching environments

Triacs Applications

• Industrial motor speed control systems
• Solid-state relay implementations
• General purpose AC power regulation

Triacs Procurement Notes

Verify component authenticity through authorized Littelfuse distributors or certified supply chain partners. Confirm RoHS compliance status via official datasheets before integration. Ensure storage conditions maintain moisture sensitivity levels according to manufacturer guidelines for leaded surface mount packages.

Triacs Selection Notes

Select this variant when a 600 V rating is required alongside standard gate sensitivity specifications. Compare against the QJ6004D3RP if lower gate trigger currents are necessary for specific driver interfaces. Validate thermal management requirements for the TO-252-3 package based on expected RMS current loads.

Triacs Part Context

This component belongs to the Teccor QJxx04xx family of high-power triacs manufactured by Littelfuse. The series provides standardized pinouts and electrical characteristics for designers requiring reliable AC switching solutions in compact surface-mount form factors suitable for automated assembly processes.

Triacs Replacement Considerations

The QJ6004D3RP serves as a functional substitute within the same series offering identical voltage and current ratings but with different gate trigger characteristics.
