QJ6008NH4RP

Triacs Overview

The QJ6008NH4RP is a bidirectional triac manufactured by Littelfuse, designed for surface-mount applications. It features an RMS on-state current of 8 A and a rated repetitive off-state voltage (VDRM) of 600 V. The device operates within a junction temperature range of -40 °C to +125 °C. Key electrical parameters include a maximum holding current of 35 mA, a gate trigger voltage of 1.3 V, and a gate trigger current of 35 mA. The on-state voltage is specified at 1.6 V, with a non-repetitive peak on-state current capability of 83 A or 100 A depending on the pulse width. Leakage current in the off-state is limited to 10 uA at VDRM.

Triacs Feature Summary

• Integrated thermal protection mechanism for enhanced reliability under fault conditions
• Glass-passivated junctions ensuring long-term parameter stability and device longevity
• Surface-mount SMTO-263-2 package optimized for automated PCB assembly

Triacs Applications

• Solid-state relay switching circuits
• AC motor speed control systems
• Lighting dimmer and phase control applications

Triacs Procurement Notes

Verify the specific suffix against official Littelfuse documentation to confirm exact thermal protection ratings and packaging options. Confirm RoHS compliance status through the manufacturer's latest declaration. Ensure the ordering quantity matches the available reel or cut-tape configurations provided by authorized distributors. Cross-reference the part number with the most recent datasheet revision to validate all electrical specifications before finalizing procurement.

Triacs Selection Notes

Select this component when a 600 V blocking voltage and 8 A continuous current are required in a compact SMD form factor. The integrated thermal shutdown feature distinguishes it from standard triacs, offering added safety in critical loads. Verify that the gate drive circuit can supply the specified 35 mA trigger current. Consider the SMTO-263-2 package dimensions for PCB layout constraints compared to through-hole alternatives.

Triacs Part Context

This part belongs to the QJxx08xH series of Littelfuse Triacs. The 'QJ' prefix typically denotes a specific package style or product line variant within the broader thyristor family. It shares core electrical characteristics with other 8 A triacs but is distinguished by its specific voltage rating and thermal protection integration. This series is part of Littelfuse's comprehensive power control portfolio.

Triacs Replacement Considerations

Direct replacements must match the 600 V VDRM, 8 A ItRMS, and SMTO-263-2 package. Verify if the substitute includes equivalent thermal protection features. Check for identical gate trigger requirements to ensure compatibility with existing drive circuits. Consult Littelfuse application notes for cross-reference recommendations.
