QJ8010L5TP

Triacs Overview

The Littelfuse QJ8010L5TP is a standard TRIAC from the QJxx10xx series, rated for 10 A RMS on-state current and 800 V repetitive peak off-state voltage. It utilizes a TO-220AB isolated package (L-Package) with an electrically isolated mounting tab. The device operates within a junction temperature range of -40°C to +150°C and supports non-repetitive surge currents up to 120 A at 60 Hz. Gate trigger characteristics include a maximum DC gate trigger current of 50 mA across quadrants I, II, and III, and a typical turn-on time of 1-2 µs.

Triacs Feature Summary

• Electrically isolated semiconductor device recognized under UL 1557
• High temperature capability with a maximum junction temperature of 150°C
• Glass-passivated junctions for enhanced reliability
• 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
• Static switching relays

Triacs Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm the exact gate sensitivity class and package isolation type. Ensure that the thermal management design accounts for the specified junction-to-case thermal resistance values provided in the official documentation. Confirm compliance with RoHS directives and REACH regulations prior to final procurement.

Triacs Selection Notes

Select this component for AC power control circuits requiring high surge handling and electrical isolation between the heatsink and circuit ground. The 800V rating suits general mains voltage applications. Verify that the gate drive circuit can supply the required trigger current and voltage levels specified in the electrical characteristics table for reliable operation across the full operating temperature range.

Triacs Part Context

This part belongs to the QJxx10xx series of 10 A High Temperature Standard TRIACs manufactured by Littelfuse. The series includes variants with different voltage ratings (600V or 800V), packages (TO-220 isolated, TO-220 non-isolated, TO-263), and gate sensitivities. The L-package specifically denotes the electrically isolated version suitable for direct heatsinking without additional insulation hardware.

Triacs Replacement Considerations

Compatible alternatives within the same family include QJ8010R5TP (non-isolated TO-220) and QJ8010N5TP (surface mount TO-263). Substitutes must match the 800V blocking voltage, 10A current rating, and TO-220 package footprint if isolation is not strictly required.
