QJ8006NH4RP

Triacs Overview

The Littelfuse QJ8006NH4RP is a snubberless Alternistor triac rated for 800 V peak repetitive off-state voltage and 6 A RMS on-state current. It features a low holding current of 50 mA maximum and an on-state voltage of 1.6 V. The device operates within a temperature range of -40°C to +125°C and utilizes a TO-263 (D2PAK) surface mount package.

Triacs Feature Summary

• Snubberless design capability for simplified circuit implementation
• High thermal robustness with internally isolated construction
• Low holding current for reliable gate triggering

Triacs Applications

• AC motor speed control systems
• Solid state relay applications
• Lighting dimmer circuits

Triacs Procurement Notes

Verify the specific suffix 'QJ' against the datasheet to confirm the 6A rating, as generic series prefixes may denote different current capacities. Ensure the TO-263 footprint matches the PCB layout requirements. Confirm RoHS compliance status through official manufacturer documentation prior to finalizing procurement specifications.

Triacs Selection Notes

Select this component when high surge capability and snubberless operation are required in a compact surface mount form factor. The 800V rating suits medium-voltage AC applications. Evaluate thermal management needs given the TO-263 package constraints for continuous 6A loads in enclosed environments.

Triacs Part Context

This part belongs to the QJxx06xHx series of Alternistors from Littelfuse. These devices are engineered for high reliability in power switching applications. The series emphasizes mechanical robustness and thermal performance suitable for industrial and consumer electronics markets requiring efficient AC power control.

Triacs Replacement Considerations

Direct substitutes include other 800V, 6A snubberless triacs in TO-263 packages from Littelfuse or compatible manufacturers. Verify identical pinout configuration and thermal resistance characteristics before substitution to ensure circuit compatibility.
