QJ6004D3RP

Triacs Overview

The Littelfuse QJ6004D3RP is a bidirectional triac from the QJxx04xx series, housed in a surface-mount TO-252-3 (D-PAK) package. It supports an RMS on-state current of 4 A and offers a rated repetitive off-state voltage of 600 V. Key electrical parameters include an on-state voltage of 1.4 V, a gate trigger voltage of 1.3 V, and a gate trigger current of 25 mA. The device operates within a temperature range of -40°C to +150°C and exhibits a maximum off-state leakage current of 5 µA at VDRM.

Triacs Feature Summary

• Integrated diac structure for noise-immune AC switching
• Glass-passivated junctions for parameter stability
• Surface-mount D-PAK packaging for board space optimization

Triacs Applications

• AC speed controls
• Temperature modulation controls
• Lighting controls requiring noise immunity

Triacs Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pinout and thermal characteristics. Confirm RoHS compliance status through the latest regulatory documentation provided by Littelfuse before finalizing component selection for production.

Triacs Selection Notes

Select this component for applications requiring integrated noise immunity without external discrete diacs. Ensure the circuit design accommodates the 4 A RMS current rating and 600 V blocking voltage. Verify that the TO-252-3 package thermal resistance meets the system's heat dissipation requirements under continuous operation.

Triacs Part Context

This part belongs to the Teccor QJxx04xx series of Quadrac devices manufactured by Littelfuse. These components combine a triac and a diac trigger within a single package, eliminating the need for separate assembly steps. The series is designed for reliable AC switching in environments where noise immunity is critical.

Triacs Replacement Considerations

Direct substitutes within the same family include other QJxx04xx variants with matching voltage and current ratings. Cross-series replacements like L6004D3RP differ in sensitivity and operating temperature limits; verify functional equivalence before substitution.

Triacs FAQ
