QJ6040JH7TP

Triacs Overview

The Littelfuse QJ6040JH7TP is a bidirectional triac in the QJxx40xx series, housed in an SMTO-218 (TO-218) through-hole package. It features a rated repetitive off-state voltage (VDRM) of 600 V and an RMS on-state current (It RMS) of 40 A. The device supports a non-repetitive peak on-state current of 500 A with a maximum on-state voltage of 1.6 V. Gate triggering requirements include a maximum holding current of 100 mA, a gate trigger voltage of 1.3 V, and a gate trigger current of 100 mA. Leakage current at VDRM is limited to 20 uA. Operating temperatures range from -40 C to +150 C.

Triacs Feature Summary

• High thermal stability with a maximum junction temperature rating of 150 C for robust operation in demanding environments.
• Sensitive gate control characteristics allowing reliable triggering with low gate power requirements.
• High surge current capability providing protection against transient overloads during switching events.

Triacs Applications

• Industrial motor speed control systems
• Solid-state relay output stages
• AC power regulation circuits

Triacs Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number QJ6040JH7TP with official Littelfuse documentation. Confirm the specific suffix H7TP corresponds to the required packaging and compliance specifications. Ensure the supplier provides traceable origin data to mitigate counterfeit risks. Validate RoHS status through the latest datasheet revision before finalizing procurement orders.

Triacs Selection Notes

Select this component when a 600 V blocking voltage and 40 A continuous current capacity are required in a TO-218 form factor. The 1.6 V on-state voltage offers lower conduction losses compared to higher voltage variants. Verify that the 100 mA gate trigger current aligns with the driving circuit capabilities. Consider the 150 C operating limit for high-temperature industrial applications where standard 125 C devices may fail.

Triacs Part Context

This triac belongs to the QJxx40xx series, designed for general-purpose AC switching. It shares the 40 A current rating with other family members but differs in voltage and gate sensitivity. The QJ6040JH7TP specifically targets applications requiring 600 V isolation with enhanced thermal performance compared to lower-rated counterparts in the same package style.

Triacs Replacement Considerations

The Q6040J7TP is a related variant within the Qxx40xx series offering similar electrical ratings but potentially different gate sensitivity or thermal limits. Verify pinout compatibility and exact parameter matches before substitution. The Q6040K7TP represents another alternative with distinct gate characteristics. Always consult official replacement guides to ensure functional equivalence.
