QJ8010RH3TP

Triacs Overview

The Littelfuse QJ8010RH3TP is a high-temperature Alternistor TRIAC rated for 800 V repetitive off-state voltage and 10 A RMS on-state current. It operates in Quadrants I, II, and III with a DC gate trigger current of 10 mA maximum. The device features a peak non-repetitive surge current capability of 120 A at 60 Hz and a critical rate-of-rise of off-state voltage (dv/dt) of 450 V/μs at 800 V. Packaged in a TO-220AB non-isolated configuration, it supports an operating junction temperature range from -40°C to +150°C.

Triacs Feature Summary

• Alternistor design enables reliable switching in Quadrants I, II, and III without requiring a snubber circuit.
• High thermal performance allows operation up to a 150°C junction temperature.
• Glass-passivated junctions provide protection against environmental stress.

Triacs Applications

• AC solid-state switches
• Heater control systems
• Motor speed controls

Triacs Procurement Notes

Verify the specific suffix 'H3' corresponds to the required 10 mA gate sensitivity for your application. Confirm that the TO-220AB non-isolated package meets the isolation requirements of the target circuit design. Ensure the ordering quantity aligns with the standard tube packaging specifications provided by the manufacturer.

Triacs Selection Notes

Select this component when high commutation capability is needed for inductive loads. The 10 mA gate sensitivity requires appropriate drive circuitry compared to higher sensitivity variants. Verify that the 800 V rating exceeds the peak line voltage plus transient spikes expected in the system.

Triacs Part Context

This part belongs to the QJxx10xHx series of 10 A high-temperature Alternistors. It shares the same physical dimensions and electrical ratings as other members of the family but differs in gate trigger current sensitivity. The 'R' designation indicates the non-isolated TO-220AB mounting tab configuration.

Triacs Replacement Considerations

QJ8010LH3TP offers identical electrical characteristics in an electrically isolated TO-220 package. QJ8010NH3TP provides the same performance in a surface-mount D²PAK format. Standard TRIACs like QJ8010R4 operate only in Quadrants I and III.
