QJ8010NH3TP

Triacs Overview

The Littelfuse QJ8010NH3TP is a high-temperature Alternistor TRIAC rated for 10 A RMS on-state current and 800 V repetitive peak off-state voltage. Housed in a TO-263 (D2PAK) surface-mount package, it operates within a junction temperature range of -40°C to +150°C. The device supports triggering in Quadrants I, II, and III with a maximum DC gate trigger current of 10 mA. It features a non-repetitive surge current capability of 120 A at 60 Hz and maintains an off-state leakage current of 10 µA at 25°C.

Triacs Feature Summary

• Alternistor design enables reliable commutation in highly inductive load applications without requiring external snubber circuits.
• Three-quadrant sensitivity allows operation in Quadrants I, II, and III for flexible AC phase control and switching.
• Glass-passivated junctions provide protection against environmental stress and ensure long-term reliability.

Triacs Applications

• AC solid-state switches and static switching relays
• Heater control and lighting dimmer circuits
• Motor speed control systems

Triacs Procurement Notes

Verify the specific suffix 'H3' confirms the 10 mA gate trigger sensitivity required for the application. Ensure the TO-263 footprint matches the PCB layout. Confirm RoHS compliance status through official Littelfuse documentation before finalizing procurement specifications.

Triacs Selection Notes

Select this component when high commutation performance is needed for inductive loads. The TO-263 package facilitates surface-mount assembly. Verify that the 10 mA gate drive capability aligns with the control circuit output. Consider thermal resistance values for heat sinking requirements in enclosed environments.

Triacs Part Context

This part belongs to the QJxx10xHx series of high-temperature Alternistors from Littelfuse. It shares the 10 A current rating and 800 V blocking voltage with other variants but differs in package type and gate sensitivity. The 'N' designation indicates the TO-263 surface-mount form factor.

Triacs Replacement Considerations

QJ8010R4TP and QJ8010N5TP are available within the same product family. Substitution requires verifying package compatibility and ensuring the gate trigger current specifications meet the driving circuit requirements.
