QJ4006DH4TP

Triacs Overview

The Littelfuse QJ4006DH4TP is a bidirectional triac in the QJxx06xH series, housed in a TO-252-3 (D-PAK) surface-mount package. It features an RMS on-state current of 6 A and a rated repetitive off-state voltage of 400 V. The device exhibits a maximum on-state voltage of 1.4 V, with gate trigger requirements of 1.3 V and 35 mA. Leakage current at rated voltage is limited to 10 uA. It operates within a temperature range of -40 C to +150 C.

Triacs Feature Summary

• Integrated high-reliability design for AC switching applications
• Surface-mount construction for automated assembly efficiency
• High thermal stability supporting elevated operating temperatures

Triacs Applications

• AC power control circuits
• Lighting dimmer systems
• Motor speed regulation

Triacs Procurement Notes

Verify component authenticity through authorized Littelfuse distributors or certified partners. Confirm RoHS compliance status via official datasheets before integration. Ensure storage conditions maintain device integrity. Validate part markings against manufacturer specifications to prevent counterfeit introduction into supply chains.

Triacs Selection Notes

Select this component when a 6 A RMS current rating and 400 V blocking voltage are required in a compact D-PAK footprint. Consider the specific gate trigger characteristics for driver compatibility. Evaluate thermal management requirements given the 150 C maximum junction temperature limit and surface-mount heat dissipation constraints.

Triacs Part Context

This part belongs to the QJxx06xH series of triacs from Littelfuse. The series offers various voltage ratings while maintaining consistent current handling and packaging standards. This specific model provides a 400 V variant suitable for lower voltage AC mains applications compared to higher voltage counterparts in the same family.

Triacs Replacement Considerations

Direct substitutes include other 6 A, 400 V triacs in TO-252 packages from Littelfuse or competitors. Verify pinout compatibility and electrical parameter equivalence. Check for equivalent thermal resistance values to ensure similar performance under load.
