QJ8010NH3RP

Triacs Overview

The Littelfuse QJ8010NH3RP 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 typical gate trigger current of 10 mA and a maximum holding current of 15 mA. It features a non-repetitive surge current capability of 120 A at 60 Hz and maintains an on-state voltage of 1.6 V.

Triacs Feature Summary

• Alternistor design enables operation in Quadrants I, II, and III without requiring a snubber network.
• Glass-passivated junctions ensure long-term parameter stability and reliability.
• Electrically isolated semiconductor device recognized under UL 1557.
• Solid-state switching eliminates arcing, contact bounce, and associated voltage transients.

Triacs Applications

• AC solid-state switches and static switching relays
• Heater control and lighting controls
• Motor speed control applications

Triacs Procurement Notes

Verify the specific suffix 'H3' indicates the 10 mA gate sensitivity variant required for the application. Confirm the 'N' designation corresponds to the TO-263 surface mount package. Ensure the ordering code matches the exact voltage rating of 800 V. Cross-reference the manufacturer's latest datasheet for any potential revisions to thermal or electrical characteristics before finalizing procurement specifications.

Triacs Selection Notes

Select this component when high commutation performance is needed for extremely inductive loads. The Alternistor topology allows for simplified circuit designs by removing the need for external snubber networks. Verify that the gate driver can supply the specified 10 mA trigger current across the full operating temperature range to ensure reliable turn-on in all three supported quadrants.

Triacs Part Context

This part belongs to the QJxx10xHx series of 10 A high-temperature Alternistors. It shares the same core electrical ratings as other variants in the family but differs in its specific gate sensitivity and physical package configuration. The TO-263 form factor distinguishes it from through-hole options like the TO-220L or TO-220R packages available within the same product line.
