QJ8010NH4RP

Triacs Overview

The Littelfuse QJ8010NH4RP is a 10 A Alternistor TRIAC in the QJxx10xHx series, housed in a TO-263AB (D2PAK) surface-mount package. It supports an 800 V repetitive peak off-state voltage and operates within a junction temperature range of -40°C to +150°C. The device features a maximum gate trigger current of 35 mA across Quadrants I, II, and III, with a typical on-state voltage of 1.6 V at 14.1 A peak. It provides a non-repetitive surge current capability of 120 A at 60 Hz and maintains a holding current maximum of 40 mA.

Triacs Feature Summary

• Alternistor operation in Quadrants I, II, and III for high commutation performance
• Glass-passivated junctions for parameter stability
• Electrically isolated semiconductor device recognized under UL 1557
• Restricted RFI generation depending on activation point

Triacs Applications

• AC solid-state switches and static switching relays
• Heater control and motor speed control systems
• Lighting controls and light dimmers
• Power tools and lawn care equipment
• Home appliances including brown goods and white goods

Triacs Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm the exact package type and lead form dimensions. Ensure that the selected component matches the required thermal resistance characteristics for the intended heat sinking configuration. Confirm RoHS compliance status through official Littelfuse documentation prior to final procurement decisions.

Triacs Selection Notes

Select this component for applications requiring high temperature operation up to 150°C and robust surge handling capabilities. The Alternistor design eliminates the need for external snubber networks in highly inductive load scenarios. Verify that the gate drive circuitry can supply the specified 35 mA trigger current across all three operating quadrants for reliable switching.

Triacs Part Context

This part belongs to the QJxx10xHx series of 10 A High Temperature Alternistors. The series includes variants in TO-220AB isolated and non-isolated packages alongside the TO-263 surface-mount option. All devices share common electrical ratings for RMS current and surge capacity while differing in package-specific thermal characteristics.

Triacs Replacement Considerations

QJ8010NHyTP serves as a tube-pack alternative within the same series. Other family members include QJ8010LH4RP and QJ8010RH4RP, which offer identical electrical specifications but utilize different physical packages.
