QJ8010RH5TP

Triacs Overview

The Littelfuse QJ8010RH5TP is a 10 A high temperature Alternistor TRIAC rated for 800 V in a TO-220AB non-isolated package. It operates across Quadrants I, II, and III with a maximum junction temperature of 150°C. Key electrical parameters include an RMS on-state current of 10 A, a peak non-repetitive surge current of 120 A at 60 Hz, and a gate trigger current of 50 mA. The device features glass-passivated junctions, a holding current of up to 50 mA, and a typical on-state voltage of 1.6 V.

Triacs Feature Summary

• Alternistor operation in Quadrants I, II, and III for high commutation capability
• Glass-passivated junctions for enhanced reliability
• Electrically isolated semiconductor device recognized to UL 1557
• Solid-state switching eliminates arcing and contact bounce

Triacs Applications

• AC solid-state switches and phase control applications
• Heating and lighting controls
• Motor speed controls
• Power tools and lawn care equipment
• White goods appliances

Triacs Procurement Notes

Verify the specific suffix 'H5' confirms the 50 mA gate trigger current requirement for your circuit design. Confirm the TO-220AB R-package matches your thermal management strategy. Ensure the component meets RoHS compliance standards required by your manufacturing process before finalizing orders.

Triacs Selection Notes

Select this part when high commutation performance is needed for extremely inductive loads without snubber circuits. The 800 V rating provides adequate margin for standard AC line voltages. Consider the 150°C junction temperature limit for high ambient environments where standard TRIACs might fail prematurely.

Triacs Part Context

This component belongs to the QJxx10xHx series of 10 A high temperature Alternistors. It shares the same core thyristor structure as other variants in the family but differs in gate sensitivity and package type. The 'R' designation specifically indicates the non-isolated TO-220AB mounting style common in industrial power modules.

Triacs Replacement Considerations

Direct substitutes within the same series include QJ8010LH5TP (isolated TO-220) or QJ8010NH5TP (TO-263). For standard TRIAC functionality in Quadrants I and III only, consider QJ8010R5TP. Verify pinout compatibility and thermal resistance differences when swapping packages.

Triacs FAQ

Does the QJ8010RH5TP operate in Quadrant IV?

No, the Alternistor TRIAC does not operate in Quadrant IV. It is designed for use in Quadrants I, II, and III.

What is the critical rate-of-rise of off-state voltage (dv/dt)?

For the 800 V variant, the minimum dv/dt is typically 700 V/µs at TVJ = 150°C with the gate open.

Is the mounting tab electrically isolated from the Gate?

No, the TO-220AB R-package has a non-isolated mounting tab that is common with the MT2 lead.
