QJ8016NH3RP

Triacs Overview

The QJ8016NH3RP is a Snubberless HT Alternistor triac rated for 800 V repetitive peak off-state voltage and 16 A RMS on-state current. It features a low holding current of 50 mA maximum and gate trigger parameters of 2.5 V and 80 mA. The device operates within a junction temperature range of -40 °C to +150 °C, with a non-repetitive peak on-state current capability of 200 A. Packaged in an SMD TO-263 (D2PAK) case, it exhibits a typical on-state voltage of 1.6 V.

Triacs Feature Summary

• Snubberless design enables direct connection to microprocessor drivers without external snubber networks.
• High thermal performance supports operation up to 150 °C junction temperature.
• Low holding current facilitates reliable turn-off in sensitive applications.

Triacs Applications

• Solid-state relays
• Motor control circuits
• Lighting dimmers

Triacs Procurement Notes

Verify the specific suffix '3' against the manufacturer datasheet to confirm the exact gate trigger characteristics and package variant. Ensure the ordering quantity aligns with the manufacturer's standard reel packaging requirements. Confirm RoHS compliance status through official Littelfuse documentation prior to final procurement decisions.

Triacs Selection Notes

Select this component for applications requiring high surge handling and simplified circuit topology due to its snubberless nature. Consider the 800 V rating for medium-voltage AC loads. Evaluate the TO-263 package thermal resistance against the system's heat dissipation requirements to ensure reliable operation at the specified 16 A current level.

Triacs Part Context

This part belongs to Littelfuse’s HT Alternistor family, designed for robust AC power switching. It replaces legacy through-hole devices with surface-mount capabilities while maintaining high reliability. The series is engineered for industrial and consumer applications demanding efficient thermal management and compact form factors.

Triacs Replacement Considerations

Cross-reference with QJ8016NH4RP for variations in gate sensitivity and holding current. Verify pinout compatibility with existing PCB layouts when substituting other TO-263 triacs from different manufacturers.
